Who can truly claim to know the ultimate origin of David Cross's hatred of Jim Belushi? Is it one comic's disdain for another's hackery? Does Cross feel it necessary to defend the deceased John Belushi's comedic legacy from his brother Jim's tomb raiding? Or is it just a specious vendetta created for the sake of awkward tragic theater? In any case, enjoy the above clip of Cross crashing the stage during a set by Jim Belushi's Blues Brothers rip-off band. Cross's nimble little douche-dance and gaping grin pretty much say it all.
