A husband and wife decide they need to spice up their sex life.
The wife buys a pair of crotchless underwear, puts them on, and goes into the bedroom.
She seductively asks her husband,
“Hey Honey, do ya want some of this?”
The husband takes one look at her underwear and replies,
“Hell no! Look what that thing does to underwear!”
