I could almost see getting this one, too.
Me:  "If I ever got a tattoo, I've decided what I would get and where I would get it."

Husband:  "What and where?"

Me:  "I'd get it on the bottom of my foot and it would say 'Do not store at temperatures below 50°'."

Husband:  "You're a weirdo."

Me:  "Then when I get cold, I can just take my shoe off and show my foot and say 'See!  It's too cold!'."

Husband:  "Wow..."

Me:  "And the other foot would say 'Warning:  Contents under pressure.'."
