Jay Leno

It was the second straight time that replacing 'The Tonight Show' host left NBC with egg on their face.

The 74-year-old comedian had been staying at a hotel that was at the top of a heightened area of land and hadn't realized just how steep it was.

The late-night chat fest will air repeats on Fridays.

Leno was reportedly hospitalized with burns to his face.

By all accounts, he was polite and humble.
