My husband would kill me if he knew I was telling everyone this but it is sooo worth it!
When we were traveling home from a funeral, we decided to stop at a rest stop to change out of our formal clothes into to travel clothes.  He was so worried that people would think that was wrong to do but I told him to just do it anyway.
Well, when I was in the womens restroom changing, I noticed on the floor in the stall next to me, was a bag with clothes in it.  I was so excited to tell DH that there was another person changing too.
I finished changing, got out of the stall and went to wash my hands.  At the time, the door to the stall next to mine opened and I looked up to see who it was in the mirror.  It was DH!!!!!!  
 
He looked at me, looked around (probably for urinals), and then bolted out of the restroom!!!
I was laughing too hard to say anything!  The bad thing is there was a little girl (probably about 9 or 10) at the sinks who saw him.  When I left, I told him we had to get out of there before she told her mom there was a pervert in the bathroom!!!
