Mark Sweeney

If you ask him, or check out his media kit, Mark Sweeney will tell you he's a "professional comedian," even though his credits also include acting roles in "Boston Public," "The Visitor," and "Days of Our Lives." Along with those TV programs, Sweenz has also starred in several independent films which leads us to believe he's done a lot of porn. The four years he spent in the US Marines were forgettable, either that or he just can't remember them. Though his military history is a bit fuzzy, he's constantly being reminded that at some point he attended college, which is why he's still on the run from the student loan collectors. Mark Sweeney has also recently written his first book, Court Jester: The Making of a Comedian. Follow Mark on twitter.
