Congenialness Puns

I work a cancer hospital and schedule patients for surgery and procedures and stuff. I had this one couple who I knew I would like as soon as they sat down. The first thing the man says to me “you wanna hear a joke?” Me “ah, of course!” ....a few moments of silence go by... dad “did you hear about that actress? I think she played in miss congeniality? It was Reese something? She committed suicide.” Totally buying the story I go, “are you serious!? Reese Witherspoon!?” And with out a beat he says “No, with a knife.” And I looked at him for a few seconds to comprehend the joke and then lost it! I know this is probably old but it’s a classic.
