Doing an Always Sunny rewatch and man, in an already amazing show this episode still manages to stand head and shoulders above the rest and most live action comedy. The humor/writing is all there, but the second half of the episode takes the premise of the health inspector visiting Paddy's to new heights.
The execution of the "one shot" realtime scheme of fooling the health inspector is just so perfect, with seamless setup and payoff, you appreciate it more and more in every rewatch. Masterfully put together and has got to be one of the top five episodes of any half-hour comedy ever made.
"Dinner Party" from The Office and "The Marine Biologist" from Seinfeld are runners up tho.
Can anything top or come close?
