piston cup

Scene: We're making Peanut Butter & Jelly Sandwiches for lunch
Characters: son, daughter & mama

S: I want triangles - (to the daughter) do you want squares?
D: ya, I want squares
M: do you want squares or triangles?
D: squares, please, please, please (while bouncing)
M: okay.
S: mom, you are the best maker of squares. I bet if there was a contest, you'd win the piston cup.

M: (in my head) oh ya! I've mastered cutting squares in sandwiches... FINALLY!
