What to do for a talent show?

There is this mini talent show for my p.e. cl and I'm doing it with 2 other girls (I am a girl) and we have no clue what to do! We only have 1 day to come up with something because we are procrastinators. 2 things that are being done are : a really long handshake ,and these 2 girls are flag twirling. Help?!
