The sketches on the walls refers to a particular room in a house in Queens, New York, where titles of sketches were literally written on the wall. The house was where a few members of the Whitest Kids had lived before landing a deal with Fuse to make a TV show.

They had originally taped up pieces of paper with sketch ideas onto the wall, but when they were still working on a pilot, Trevor had met up with some executives and told them that the troupe had sketch ideas on the wall. The execs took it as if they had actually written them on the wall. Rather than correct them, Trevor returned to the house, took all the paper down and started writing up ideas on the wall with markers.

The legendary room can be seen in Day 10 of Whiskey.
