Colin Quinn, the "Saturday Night Live" alum, was already joking about it days after a heart attack interrupted his busy touring schedule.
The 58-year-old Quinn took to Twitter on Monday to let friends and foes alike know he's "starting a list of those who didn't 'check in' yet," five days after his Valentine's Day health emergency, The Associated Press reported.
The deep-thinking comic thanked the doctors and nurses at his New York hospital, saying they "realized they had a precious jewel of comedy in their hands."
Quinn announced his heart attack last week, saying on Twitter his heart broke on Valentine's Day, "literally." He said he was doing well but if he dropped dead "you would see a funeral like Al Capone!"
He says the attack made him reflect, realizing "we aren't guaranteed tomorrow."
