I'm an amateur stand-up and am adding some prostate cancer jokes to my set:

"I'm OK now, but when I first found out I had prostate cancer I went to the station to throw myself in front of a train. Fortunately, it was Amtrak so the train never showed up."

"I have a great support system. If I had $1 for every person who's helped me through this, I'd have $2.35."

"Prostate cancer awareness and testing is great, but please you still shouldn't let the guy by the bus station give you a prostate exam even if it's free."
