this is a classic comedy bit from a National Lampoon comedy album, a Mr. Rogers Neighborhood parody, for non-Americans Mr Rogers was a very famous childrens show host on PBS for decades, a man so sweet and gentle and fond of children that it made you think to yourself 'i hope the authorities are watching him'.
Mr Rogers interviews an African American jazz bass player who stops by Mr Rogers Neighborhood. Christopher Guest plays Mr Rogers and a very young Bill Murray plays the bass player.
This brings back memories of being in my bedroom with buddies stoned cracking up listening to this.
