Craig Ferguson Gets Serious

Craig Ferguson has been making late-night audiences laugh since 2005. The "Late Late Show" host and former "The Drew Carey Show" funnyman has often made light of his personal demons, but tonight on ET he shares details of his darker days with our own Mark Steines.

"I woke up in a sort of area above a bar, and I thought I'll have to go and kill myself," Craig reveals about one of his lowest moments -- a Christmas morning after he had been drinking with a bartender the whole night before. "I was very mad. And I thought I'll have to go and kill myself, so I'll go and swan dive off Tower Bridge in London."

Instead, Craig ended up having a sherry and spending the day with the bartender and his family -- and forgot all about wanting to kill himself.
