WATCH: Kim Kardashian Cameos on '30 Rock' Live Episode

The East Coast and West Coast feeds of Thursday night's live show had some pretty interesting differences -- which we've kindly broken down for you

If you're based on the West Coast, then you were lucky enough to see one very special celebrity cameo in Thursday night's live 30 Rock episode that you wouldn't have seen on the East Coast: Kim Kardashian!

The 31-year-old reality star had brief appearances at the beginning and end of the episode that aired out west. Apparently there was no better bathroom in all of 30 Rockefeller Center than Jack Donaghy's (Alec Baldwin) office, so that's where Kenneth (Jack McBrayer) escorted her to use the lady's room. Where did she go after she walked into that corner? Is there some secret room in Jack's office that we don't know about? Maybe, since it's later revealed that she managed to break his toilet! Watch the West Coast episode below (with Kim first appearing shortly after the one-minute mark).

East Coasters were treated to another awesome celebrity cameo instead. Paul McCartney stopped by Jack's office, also in dire need of a toilet. Except instead of breaking the bowl, it was later revealed that Sir Paul lost his memory while in there. What is up with that bathroom?

That wasn't the only difference between the two different feeds. On the East Coast, Jon Hamm (who also partook in both episodes' Amos 'n' Andy spoof) played sexist newscaster David Brinkley, while real-life anchorman Brian Williams took that duty for the West Coast show. And a kiss shared by Alec Baldwin and Scott Adsit only aired in the east, and Leo Spacemen's ancestor Dr. Harold Spaceman was a Nazi instead of gay on the East Coast. There are plenty of other differences interspersed, which just provides us with more incentive to watch both versions and obsess over all the small little changes. (Check out the East Coast feed below!)

One thing is clear though: The homage to live television was a total success. 30 Rock hit a six-week high last night with 3.5 million viewers. But it helps that the episodes were actually hilarious!

It helped that many of Tina Fey's former Saturday Night Live cast members -- like Amy Poehler, Jimmy Fallon, Chris Parnell and Fred Armisen -- were on hand to help ease the process. It might get a bit old to do many more of these live episodes, but we would be perfectly happy seeing another one or two before the show goes off the air.
