Riddle: how do you go for a 5 mile run and gain 5 pounds?

Clue 1: When I came home, my pants were two inches longer.

Clue 2: I combined my morning shower with my run.

Answer: The pineapple express has come to town. That's warm, very WET weather that supposedly comes from the tropics. There's even an urban flood watch on.

Good thing I didn't know how hard it was raining when I started out. I never would have gone.
