Imaginary jokes

My girlfriend is like the square root of -100

An absolute 10, but also imaginary.

Courtesy of my 11-year-old: Dad, what's the difference between a humorous reference and an imaginary bread?

One is a wry allusion and the other is a rye illusion.

My girlfriend and I have a complex relationship.

I'm the real part and she's the imaginary part.

My friends laughed at me when I told them I had a hot date and they say she was imaginary...

Well, jokes on them - they're imaginary too.

Son: Dad, I have an imaginary girlfriend.

Dad: You know, you could do better.

Son: Thanks Dad, that means a lot.

Dad: I was talking to your girlfriend.

I'm Jealous of my imaginary friend because he has a real friend
