It's hard to believe, but one thing on 30 Rock is not funny.
Actor Grizzwald "Grizz" Chapman, who plays one-half of Tracy Morgan's security detail on the NBC comedy, is facing kidney disease that's no laughing matter.
The 35-year-old star appears on Tuesday's episode of The Dr. Oz Show, where he tells Dr. Mehmet Oz of his struggles.
The 6-foot-11, 378-pound actor is on dialysis three times a week for severe hypertension, the New York Daily News reports. He's currently on the waiting list for a kidney transplant, but has to lose 75 pounds before he can even be considered a candidate.
Regardless of his weight loss, though, that waiting list is nearly five years long.
Of course, the outlook on his hypertension didn't always look this grim.
