King of the Hill Easter Egg - She Don't Like Cocaine

In the episode "The Wedding of Bobby Hill", towards the beginning when Hank goes to Boomhower's house and gets Bobby, they are walking through the kitchen and there is a guy in the background with a long coat on. At first he is just standing, then right before Hank and Bobby stop walking, you can see him bend down to snort a line of cocaine (I guess) off of a table. You have to look carefully to see it.
