5. WORST: Martin Lawrence
Martin Lawrence only hosted "Saturday Night Live" once, but it was enough to get him banned from the show for life. The comedian made crude, inappropriate jokes about women's genitalia and personal hygiene, a move that was frowned upon by the "SNL" staff. Lawrence's monologue has since been edited out of reruns. —XFINITY Entertainment Staff (Photos: NBC)
