Yours truly and the Perfesser were at a M&G recently.  We were standing at adjacent urinals when the Perfesser looked at me and said, "I'll be you were born in Dayton, Ohio."

"Why, that's right," I said in surprise.

"And I'll bet you were circumcised when you were three days old."

"Right again, But how'd you-----"

"And I'll bet it was done by old Doc Steadman."

"Well, yes, but how did you know? I asked in amazement.

"Well, old Doc, always cut them at a sixty-degree angle," explained the Perfesser, "and you're pissing on my shoe."

Oops!  Sorry Perfesser.

I hope you don't mind me personalizing an oldie, but goodie.

No, but I may ask you to wipe it up at the next M&G.

Actually, I'm honored to be included in the humor. Just don't do it in the RW.
