Tube man Puns

one of the exibits was showing kids centripital force by them putting a penny or nickel in a slot and watching it roll around a tube and be held against the sides even when it was rolling horizontally. really cool stuff

my dad looks at it and says "man, talk about money down the drain."

If I were to easily kill a fellow with a drinking tube.

My self defense plea would be a straw man argument.
