My fav episodes and the reason:
Righteous Brothers (The slashcest hints)
Making a Stand (The slashcest hints and the funny flashbacks to when they're kids)
Prison Break-In (The riot and the scene where Michael and Gob are caught in what looks like a 69 position (Yes, I am a MichaelGob fangirl, deal with it))
Family Ties (Nelly, who was totally awesome, and Gob acting like a vouyer (he was in the room when Nelly was coming onto Michael))
My Mother the Car (Gob coming to Michael's rescue, George Michael and Maebey seeing an R-rated movie about cousin lovin', and Lucille being Lucille)
Beef Consomme (Michael's guilty concience and the fighting on the courthouse steps (Michael attempting to climb up a tree to get away from Gob, rofl))
Sad Sack (Gob's hilarious way of motivating Buster)
Exit Strategy (George Michael and Maebey getting closer, and Gob staying in jail out of ignorance)
Cabin Pressure (Gob's obliviousness and his line about the sleeping bags)
The Sword of Destiney (Hints that Gob was planning an 'accidental' death (there's no way he could have been that stupid))
