What is the dumbest thing you have seen while on the road?

When we left the campgrounds a few weeks ago, a whole family was brushing their teeth at the dump station...ewww!!! I do remember a funny story my dad used to tell. He was on the exit ramp slowing down and he looked over and some guy had a boat just like his. "Expletive", that boat looks just like mine. "Expletive", it is my boat! The trailer had come loose and was passing him on the left. The story is from the 1950s or 1960s so I never remember how it kept rolling. Dad is gone now, but we still laugh about that one.
