Oooo...I have a great story to go along with this. Years ago there was a shopping center built near me. Whoever designed the parking lot was obviously stoned because at first it was cone shaped, then was repainted to make only slightly more sense.
Anyway...one day the husband and I were waiting to find a spot behind an elderly lady with handicapped plates. (all the handicapped spots were taken.) As she got ready to pull into a spot, a young guy came from the other direction and took the spot.
I rolled down my window and waited....

As he got out, I yelled to him, "I hope you never get OLD!".
He looked at me and replied, "I hope you never get UGLY!!"

A moment of deafening silence ensued, as a look crossed his face that could only mean one thing ("oh fuck....that is SOOOO not what I meant to say....")
Jackal and I sat there in the parking lot, laughing to the point of tears at this guy's completely inappropriate and unintentional comment.
When we got into the store, he was right there looking at something and we were STILL laughing, only this time right in his face.
