Tracy Morgan suffered a medical scare at the Sundance Film Festival on Sunday when he lost consciousness after an awards ceremony. The comedian's publicist, Lewis Kay, quickly ruled out drugs and alcohol, blaming the collapse on altitude and exhaustion instead. However, the trip to the hospital didn't keep Morgan out of commission. The actor was back in New York by Tuesday and tweeting jabs at costar Alec Baldwin. "On the set of 30 Rock, just walked past @alecbaldwin and said Top That!," he wrote, referencing Baldwin's recent kerfuffle with a certain airline.
