House Party

Short Answer: Other reasons to host a house party

Does there need to be a reason to throw a house party? The franchise seems to think so. In several of the plots, the need to raise money arises, so a party is thrown and admission is charged. In several cases, there is a mansion to take advantage of-- including the 2023 installment, which was released just a bit more than a week ago as I write this (It was LeBron James' mansion; he was one of the producers). 

But there are other reasons to throw a house party:
1) a Realtor, wanting to show off a hard-to-sell mansion's capacity for entertaining, throws a house party in it.

2) A switcheroo-- instead of kids throwing a party because their parents are away, the parents throw a party to celebrate their kids being away for the summer. 

3) The party is to celebrate a victory by a celebrity who ran for mayor, but at the house is full of secrets that, when stumbled upon by the guests, would ruin her budding political career.

4) A blue-collar couple win the lottery, buy a mansion and throw a party. The husband invites other rich people because he wants to ingratiate himself with the "one percenters." But the wife invites all her blue-collar friends from their past. Some of each group prove good guests... but some of each group do not. 

5) A version of "Mad Mad Mad Mad World"-- an eccentric millionaire is getting divorced. His wife gets the mansion. Before he hands it over, he wants to trash it. But he's too lazy. So to get others to trash it, he  throws a house party... at which he announces that there is ten million dollars hidden somewhere in the house. The guests (played by every available celebrity) begin to rip the place completely apart looking for it.
His joke, though, is that it's not ten million in CASH-- the furniture, fixtures, art, etc. taken together are worth that. But looking for the cash they think he means, people break all the furniture, rip the paintings out of their frames, smash the huge vases and antique lamps, and so on.
But then the wife flips the script on him-- she shows up with bulldozers to knock the whole place down! She always thought it was hideous, and it reminds her of him. In any case, it was riddled with mold, termites, and the ravages of age; the real value is in the land itself. Meanwhile, the public emerges from their efforts and realizes they have been lied to... and chase the millionaire into the next county.

6) In some of the movies, someone wants to be at a party because he wants to see his crush there. But what if that was the point of the party? A guy has a crush and his rich female friend says, "You can't throw a party and invite her... but I can, so you can meet her." At the party, they do everything to get the two together, but circumstances keep intervening. But then the guy realizes that the girl he was so infatuated with is really shallow, and the girl who threw the party is really amazing. In the last scene, he kisses his friend and she says, "I don't understand-- I threw this party so you could be with the girl of your dreams." He says, "Well, thank you-- it worked!"
