With the addition of Danny DeVito to the cast season two of "It's Always Sunny in Philadelphia". The always difficult, 'make it or break it' second season of any TV series (especially sitcoms) is a resounding success in this case, staying pretty spectacular from episode 1 through the season finale. Despite providing only one really classic episode in "The Gang Goes Jihad" the consistent quality of the season makes it really memorable. The writing is solid for the characters, developing them without descending to the schmaltzy, humorless 'character-based' scenes other sitcoms depend on a lot.
