How old is too old to wear a pot on your head? 

This question has been bothering me all morning long and I’m not really sure why. Perhaps it’s because I don’t want to do any real work, or perhaps because I think this picture is so cute.I’m thinking the answer is 14.  If my math is correct that brings you to 9th grade and by the time you’re in High School you probably shouldn’t be wearing pots on your head. 
I should add though that it would be entirely acceptable in certain circumstances after age 14 like as a costume or perhaps at the end of a long Saturday night in college.  So now, as I think more about this, I’ll have to throw out that previous thought.  Go ahead, wear a pot on your head.  It looks like fun.
