Fallon became well known for his tendency to break character in sketches , an attribute he himself , as well as Michaels , disliked .

During this time , Fallon parlayed his '' SNL '' success into co-hosting the 2001 MTV Movie Awards and 2002 MTV Video Music Awards , and the recording on his debut comedy album , '' The Bathroom Wall '' ( 2002 ) , which was nominated for the Grammy Award for Best Comedy Album . He also modeled for Calvin Klein . Fallon was named one of '' People '' magazine 's 50 Most Beautiful People in 2002 , an honor Fallon found embarrassing
