Joke stuck in my head

[El Dingo]

A man goes to see his doctor. The doctor tells the man he needs to stop masturbating.

'Why?', says the man.

"So, I can examine you"

This is my favorite type of joke which is why I love (the late) Mitch Hedberg.

"I haven't slept for ten days...because that would be too long"

"I used to do drugs. I still do drugs, but I used to too"

Temporal humor is the best humor.
