On the Podlink Farm, if you select the Foot and click on a specific spot on the top-left corner of the gate sign, the Foot will briefly flash. Do the same for the bottom-center of the sign and the top of the farm's silo, and a short animation will play of a nuclear missile launching out of the silo. One of the game's developers who revealed the existence of the Easter egg explained it as being a "tiny juvenile rebellion" by Viacom New Media aimed at the Viacom managers they were sometimes at odds with.
