(From a few years ago.)
So a patient went in for a snip …
Doctor: Have you ever had major surgery before?
Doctor: I can see that you’re lying to me. You have had major surgery.
Patient: What are you talking about, doc? Seriously, I’ve never had major surgery.
Doctor: You’ve had a circumcision.
Patient: But I didn’t think that was major surgery.
Doctor: Really? I bet you didn’t walk for a year afterward!
