Anal Glaucoma

From John's Online Journal: "My sister in law is a good source of jokes so here is another. Phone rings Boss: Hello Bob: Yeah, I can't come to work today Boss: Why not? Bob: I went to the doctor and he says I have anal glaucoma. Boss: What the hell is 'anal glaucoma.' Bob: I just can't see myself coming into work today. I can't see myself coming into work to day either, just don't give me drops to dilate my ass."
