Wow, these are bringing back so many memories! I can remember a whole bunch of different variations on many of these...Another one we used to do was Anna Banana...We all stood in a circle doing this clappy thing and whenever we said "Split" we all jumped a little lower into our split until someone fell:

Anna Banana plays the pian-a
All she can play is the Star Spangled Bann-a
Anna Banana SPLIT!
She's an idiot!
