'Psych' Season Finale Sneak Peek: The Many Names Of Burton Guster (EXCLUSIVE VIDEO)

One of the most reliably amusing running gags on "Psych" involves the aliases of Burton "Gus" Guster, Shawn Spencer's best friend and fellow investigator.

As the show's Season 7 finale approaches, The Huffington Post offers this compilation (above) of all the names Shawn has used for Gus this season, including "Blue Ivy Carter," "Bill Uvrights" and "Gern Blandsten." But as fans know, there were so many more.

Speaking of Wednesday's season finale, in "No Trout About It," Anthony Michael Hall plays an eccentric police consultant who comes in to help with a case that Gus, Shawn and the Santa Barbara police can't seem to crack. We can only guess at how many "Pretty in Pink" references there will be in Hall's scenes.

The "Psych" season finale airs on Wednesday, May 29 at 10 p.m. ET on USA.
