Bubble bubble, boil and trouble...

Husband and Wife are vacationing with Friends and spending time at the pool. Husband is swimming while Wife and Friends get into the hot tub. Husband joins them later and steps gingerly into the hot tub.

Husband: Wow! How hot is this water?

Friend: About 100 degrees.

Husband jumps out quickly.

Husband: It's boiling?!?!

Wife: 100 degrees Fahrenheit.

Husband: Then why are all of you red?

Wife: That's what happens when white people stay in hot water. I promise the water feels good.

Husband sits on the edge and puts his feet in the water.

Husband: Humph. White people are strange.
