Ah, hmmm. I can blow bubbles from my tongue
Great little party trick, until one lands on someone and they realize I basically just spat on them. :P

No, no, that's ok. Anything else?

I wouldn't call it useless, someone enjoys it.

I can bend my fingers really far back by themselves?

I can write near perfect with my feet xD

There are people in this world who haven't seen Mean Girls?

this I can make my palms touch

oh and this

Well yeah

I can name every PM ever in order

I can rearrange furniture

I consider myself pretty good at building Sims houses. If that's not useless then I don't know.

I can do a perfect re-creation of the Femme Fatale tour & promo performances choreography

I'm not joking, either

This tbh.

I can decork a champagne/wine bottle with a knife without breaking the bottle

I win Rock Paper Scissors 70-80% of the time. The trick is to use rock first because people normally use scissors first round.

I can crack my nose

Pretty sure that's just déjà vu, sis.
