Pants. Pants. Pantspantspantspantspants.
It just sounds funny.
I've decided to incorporate a new expression into my personal vernacular, and have co-opted some of my friends into the conspiracy. The phrase:
"That really irons my pants."
Use as you will. It's always funny.
In case there's still any question as to the solidity of my thesis, try this one instead:
"That really irons my shirt."
Nothing. Therefore, the word "pants" is funny.
