Look-alike

Dr. Attending: "You know who you look exactly like?"

Patient: "Who?"

Dr. A: "Danny DeVito!"

Patient: "..."

Dr. A: "Has anyone ever told you that before?"

Patient: "Yeah."

Dr. A: "Well, you really do look an awful lot like him."

Patient: "Gee, thanks."

Dr. A: "Maybe it's your accent."

Patient: "Back when I had a goatee, people used to tell me I looked like Andre Agassi."

Dr. A: "..."

(I didn't think the guy looked all that much like Danny DeVito. Or Andre Agassi.)
