Imaginary memes

I call my friends Dodo birds. Because they don't exist.

When someone has an imaginary friend, you call them weird and crazy.

But when a group of people have an imaginary friend, you call it religion. :)

A son tells his father, "I have an imaginary girlfriend."

The father sighs and says, "You know, you could do better."

"Thanks Dad," the son says.

The father shakes his head and goes, "I was talking to your girlfriend."
