Nostalgic Anonymous

Here is a joke about nostalgia, which is my permanent mental condition. It is not my joke, I am not sure where I heard it first or where it comes from, but it is funny because it is true (in my case anyway). So here it is:

"I was in Nostalgic Anonymous, but I left the group, because the meetings are not what they used to be."

I hope you enjoyed. Like I said, it is very, very, very me.
