Get it? Because it's an erogenous zone?

The store has a lot of traffic, and traffic is made by people, and people can be disgusting. I was helping a woman find a bra, and after opening a storage drawer to look for the particular color she wanted we both noticed a huge, sticky, pink wad of gum stuck on the inside of the drawer.

"Sorry Ma'am, usually our bras are out of the store by the time they get spit all over them."
