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. **Part two originally aired as an episode of "Hello, Larry".
