Remembering this one from elementary school (but you had to do it whilst standing:

Mr. Dan Dan Dan
Mr. Dan Dan Dan
Hug me
Kiss me
Say that you love me
*stretching legs* I love you

Mr. Dan Dan Dan
Mr. Dan Dan Dan
Punch me
Kick me
Say that you hate me
*stratching legs* I hate you

This goes on until everybody falls and the person that could stretch the most and keep on standing wins.

Another one is:

My mother your mother lived down street
18 19 marble street
And every time they had a fight
This is what they say all night

Boys go to Jupiter to be more stupider
Girls go to mars to be rockstars

Itsee bitsee lollipop, itsee bitsee bo
Itsee bitsee lollipop, the boys love you!

----
Last:

Ameena *clap clap clap*
Superstina *clap clap clap*
Lazy boys *clap clap clap*
Super girls *clap clap clap*
*now faster*
Ameena
Supersteena
Lazy boys
Super girls
S
T
O
P
STOP
*no one moves*
The first to move loses and the last to stay in one position without moving wins.
