Croak

Patient: Doctor, Doctor I keep thinking I'm a frog!
Doc: So what's wrong with that?
Patient: I think I'm going to croak!

Gassy Granny

An elderly lady goes into the doctor and tells him - "Doctor, I don't know what the problem is, but I've been farting all the time. It's not really a problem socially because they don't make any noise and don't smell. I just can't stop farting all the time. In fact while I've been in here I must have farted at least 20 times." The doctor nods and gives her some pills. "Here take these for two weeks and come see me again when you are done." So she takes the pills and returns two weeks later as instructed. Infuriated, she confronted the doctor. "What kind of medicine is this? I'm still farting just as much? They still don't make any noise, but now they stink terribly!" The doctor nodded, "It's alright, now that we have your sinus' cleared up, we'll work on your hearing next!"

I Have Bad News

The doctor tells his patient: "Well I have good news and bad news..." The patient says, "Lay it on me Doc. What's the bad news?" "You have Alzheimer's disease." "Good heavens! What's the good news?" "You can go home and forget about it!"
