Simpsons:Hit and Run, The Easter Egg - Andoid Dungeon Record

First, go to level 6, Bart's final level. After, select any mission. Before activating the mission, go into the Android's Dungeon. As soon as you walk in, turn left and look on the wall. A record is hanging on the wall, but with closer inspection, it is the record, "Sax on the Beach", the one Lisa was trying to buy for $500 in the episode "Round Springfield".
