Here's some of his stand-up material from his "One Night Stand" HBO special in 2005.
Here's a segment from a 2006 episode of Opie & Anthony where Lil' Jimmy talks about the pranks he did as a child.
Lil' Jimmy in the Opie & Anthony studio trashes a Derek Jeter gift basket after getting stiffed from getting an autograph and overall being blown off by the Yankee shortstop.
