Overheard

The showers at the campground are free for cold water, and $3 for hot water. There is also a pool which is $4 for the day.

Overheard, man talking to a woman who I assume is his wife:

Woman: I cheated, I paid for the hot shower.

Man: but you went to the pool today!

Woman: I know, but I didn't get in the water.

Man: the whole reason we paid for the pool is so we wouldn't have to pay for your shower!!
