Comedian Lisa Lampanelli is hysterical ... but there ain't nothing funny about how great she looks since her dramatic weight loss.

After recently undergoing gastric sleeve surgery to remove 85% of her stomach, the 51-year-old ball buster showed off her new curves in NYC on Tuesday (left) -- and looks remarkably different from  even just five months ago (right).

Lisa is no joke.
