From my childhood in the 40's in southern Wisconsin... white males, mostly, but I imagine the girls said them, too.. probably when we were 6-10 years old.

Down in the gas house, hello Pete
Did you ever get a whiff of .....'s feet

Fatty, fatty two by four
Couldn't get through the bathroom door
Had to do it on the floor

Here comes the bride,
Fair, fat and white.

(Guess we had a politically incorrect attitude toward the weight-challenged.)

School's out, school's out
Teacher let the fools out

Man... this could go on and on..
