The red dildo
 

A lady walks in to a sex shop and asks the attendant where the dildos are. He tells her they are on the back wall. She goes back to see the selection. After ten minutes or so, the attendant hasn't seen her again, so he figures to check on her, and see if she needs assistance. He asks, and she asks him, "How much for the big red one?" Trying to keep from laughing, he says, "Ma'am, the dildos are NEXT to the fire extinguisher!"
