I think it's a good trap, too!

I think it could probably be made to work in real life, assuming the person made to do the dance was adequately fit and knew how to dance.  You could do the same thing with pushups, perhaps, or jumping jacks, or any physically demanding pursuit.  (Sorry, bad gym class flashbacks....)

I'll butt out now and let others answer.   

There's no way I can let this Subject expire without "sticking my oar in:"

The Best Batgirl Trap IMO: the Siamese Human Knot, of course:

The second best, the Cat's Whiskers:

Third, the Alvino Ray Gun:



Of course, you can always go to The Batgirl Bat-Trap Homepage! and decide for yourself!

Twof is the trapmaster!  Woot!

The caviar dunk's effect on Batgirl was necessarily limited, I think, by their third season special effects budget.  They used, what? diced Jell-o or something for the caviar.  It always looked more like bits of foam rubber, to me.  You can see bits of it clinging to Batgirl after she's drawn out of the tub, but not specifically in the location Batman brushes.  We do get to see the Batgirl costume get all wet at the end of the Cat's Whiskers sequence, anyway.  The tights really bag and sag once they're soaked.   

Olga was mean, much meaner than Egghead.  He seems like a nice guy by comparison.  Perhaps that's why people seem to think that Olga reduced Egghead's impact in their joint appearances.  Hmm.  I love the interaction between Batgirl and Egghead in The Ogg Couple.  Vincent Price was her favorite guest on the show, and I think we can see a bit of how she liked him in the playful quality of their encounter.

If you look at the "free at last!" vidcap I posted for the Cat's Whiskers, you can see how the fishing line they used for the whiskers was already loosened and slipping off of her before the sprinkler was ever activated.  They didn't wrap her tightly enough for it to be too uncomfortable in reality.  It looks like an uncomfortable scene to have filmed, though.  The vidcaps also show sweat patches on the Batgirl suit (unless they filmed the sequence more than once, or out of order, and the suit was previously soaked by the sprinklers).  It must have been hot, lying there in the California sun in that costume, tied up in fishing line.

I think she was freezing less because of the temperature of the caviar than because the villains' hideout was in an icehouse or something.  The room itself was supposed to be cold, and she was supposed to be wet, although she really wasnt, as egghead noted.

Should the Saber Dance not be classified as a trap?  Hmm.

Batgirl slipped on caviar, but Olga deliberately threw the caviar under the heroine's feet.

You and perilicious are probably right about the illusory quality of the apparent smiles in the vidcaps.  I can't help but wonder, though.  I keep finding a lot of stills where she looks amused while fighting.

The Cat's Whiskers is a good trap, yes.  Cage likes all of the traps.  he can't decide which one to favor.   

"For something to be a trap does it not have to be premeditated?"

Yes.

But traps and deathtraps are different

Maybe this will help.
Deathtrap: a trap designed to Kill a superhero or spy in a bizzare manner eg Cats whiskers, Batman and Robin staked to the ground by shame in the path of stampeding cattle.
Emma Peel tied to railroad tracks on the Avengers.

Trap anything used to catch or trick, especially unexpectedly. eg Riddler set a trap for batman with the gun shaped cigarrette lighter and waiting photographer, a nice trick indeed. traps often have an element of ambush to them eg weighted umbrella KO ing B&R or Cornelia Triggering the trapdoor that caused B&R to slide into boxes where they were trapped. Paralysing gas used to (trap) incapacitate Batgirl inside Lord Fogg's cricket pavillion.

On the show arch criminals routinely use traps to capture Batman, Batgirl and Robin and then while they are helpless place them in a diabolical deathtrap to finish them off in style.

Bad Luck your car breaking down, being caught in foul weather etc etc.

Fishing line would be uncomfortable or painful if it was tied around bare skin or tied so tightly that it cut into the flesh under her costume.

Batgirl academic, Cage, tells us that it wasn't tied tightly and she had the protection of her Batgirl outfit so while it wouldn't be painful Yvonne did a great job of making it appear to be painful.

I just like to say "trap".  Maybe I should just shut my trap.  Hmm.  It's as plain as the trap on your map that Cage is out to prove to everyone how goofy & dumb he can be, with his posts tonight.   

"Batgirl academic, Cage, tells us that it wasn't tied tightly and she had the protection of her Batgirl outfit so while it wouldn't be painful Yvonne did a great job of making it appear to be painful."

Should I feel honored or offended?     I agree: she did a great job.  When did she not?

I'll try that, then.  Thank you... mutter grumble mutter... for the honor.   

BTW, 1 bat 1girl - I'm looking forward to your Origin post.
