The Alders and the Drummonds are together again in New York, and Arnold, Willis and Kimberly plan a second Thanksgiving feast with friends Diane and Ruthie. But even the huge Drummond penthouse isn't big enough to hold the exploding tempers that threaten Phil and Larry's long-standing relationship, on a special one-hour episode featuring the stars of "Hello, Larry." Morgan and all the kids get caught up in the feud when Larry learns friendship doesn't necessarily make for good business. The crossover continues on Hello, Larry S02E10 Thanksgiving Crossover (II).
