Among the tweets:

"Anyone know where I can get some good weed?"

"Is it true fat kids never get kidnapped?"

"You know you're a celebrity when strangers want to see your penis. LMAO. "

The day after the show aired, Levi Johnston and his attorney Rex Butler spoke exclusively with CBS 11 News.

Andrea Gusty: "Did you post those things on Twitter?"

Levi Johnston: "No. I've never had a twitter account. I don't know Twitter. I really don't know what it is. I don't have MySpace, Facebook. Yeah, none of that stuff is me."

Instead, Levi and his attorney say the tweets came from someone impersonating Levi on Twitter.
