I first saw this when I was in Kuwait. Some of my soldiers were watching it and I was like "WTF are you watching?" It was the episode where mac dates a Tranny so they HAD to show me the making out scene with her...you know what bulging from her jeans. And then later I saw them watching the one where they were trying to be news reporters and had Dee go into the building to save the kittens then lit it on fire.
I had all the seasons but when I moved from Ft Polk to Ft Bragg they were "lost" including the Christmas special DVD. So I had to resort to watching the edited versions on F/X when it was on.
Guess I'll have to re-purchase all the seasons cause this is a great show.
On a side note, i think it was either an episode of Criminal Minds or Law & Order were some kid killed two thugs that were trying to mug him and it was on the same "strip" as Paddy's. Since I can't remember where the episode took place I'm wondering, is that strip really in Philly or is it in L.A.? I always figured It's Always Sunny was filmed in Philly.
