I posted earlier about changing DD in her stroller when she was an infant, but I had to come back and post after reading about 'bolters'...
A few weeks ago, DH took DD (2) to a restaurant for lunch while I was running an errand. She needed her Pull Up changed so he ran her in the mens room and since it wasn't a busy day and nobody was in the restroom, he quickly changed her in the corner.
(I'm a weirdo, I try not to let DH take her to get changed in the mens room, I'd rather him leave and go change her in the car). But after he was done, he washed her hands over the sink and said stay right here next to Daddy...then he washed his hands...then not one second later, she ran to touch the urinal asking "Daddy, what is this?"
I was mortified when he told me. (of course DH heard an earful from me about WHY he shouldn't change her in the mens room...

) He said he scrubbed her hands and used Purell afterwards but I was just mortified.
