Harry and Dave are standing next to each other at the urinals doing their thing.
Harry turns to Dave and says, “Did you attend the West Street Synagogue as a kid?”
Surprised, Dave says “Yes, I did. Do I know you?”
“Was Rabbi Cohen your Mohel?” asks Harry.
“Yes, how did you know?” replies Dave.
Harry answers, “Rabbi Cohen always cuts on a slant and you’re peeing all over my shoe!”
