There was this short guy from Colorado who wanted to come to Virginia for a change and he narrated his experience in the plane he flew the day before. He had a chat with his fellow passenger and how he was greeted with “you are charming.”
“Oh you are a Charmonium” I quipped. He did not get it at first and I was a little embarrassed as I wasn’t quite clear myself why I said that. Few moments passed into the situation and I remarked, “you see, a Charmonium is a nick name for a particle that has two quarks in it, each of them is a so called charm quark. So a Charmonium is doubly charming instead of just charming.”
Another of his friend remarked how its a little tricky to get a Physics joke. On the contrary I thought how it has become a little fashionable and thats why acceptable how out-rightly sexual, Physics jokes have become.
