Do you remember some of these

[DoubleD]

Missing one, 'don't come running to me if you break your leg'

 

[Bootie]

Its all fun and games until someone gets hurt.

 

[Hedgehog]

You keep picking your nose your pull your eye out

"I can't" is the brother of "I don't want"!

Close your mouth or a fly will go in.
