South Park Easter Egg - Les Bos' Address

In the episode in which Mrs. Garrison discovers she is a lesbian and must protect her newfound bar, Les Bos, from a Persian takeover there are many interior shots of the address printed on the window above the door. These numbers appear backwards (because you're seeing them from the inside) but when you flip them around they create the number 13580. These numbers, especially on a calculator, resemble letters: 1=L, 3=E, 5=S, 8=B, and 0=O. Hence, the address spells out the word LESBO which is a main theme of the episode.
