My old bud JC is getting surgery this week and I was on the phone with him and said "Good luck under the knife" and he said "What?" and it seemed a little weird so you know how you don't say "good luck" to actors before a show, you say "break a leg" because "good luck" is bad luck to actors? I propose we have a different phrase for "good luck getting surgery" and my proposed alternate phrase is "Punch an angel."
