So not funny.
Comedian Gallagher, who's known for his signature watermelon-smashing antics, was rushed to the hospital after suffering a heart attack on Wednesday night.
The 65-year-old performer, who's full name is Leo Anthony Gallagher, complained of intense chest pains just before hitting the stage at a club in Lewisville, Texas.
The funnyman's manager said he will remain hospitalized for a couple of days, and that the attacks was "mild to serious."
Gallagher collapsed during a show at the Whiskey Bone Roadhouse in Minnesota last year, which doctors later determined was due to a heart attack.
