Because it's quite ironic how many details the Goblet of Fire movie missed from the book.
Explanation:
There are very noticeable differences in the Goblet of Fire movie and the book, and this is the more ironic and humorous one of them. There are very significant things missing in the movies; Winky the house elf is completely missing altogether, Rita Skeeter isn't as important as she was in the books, LUDO BAGMAN IS ALSO MISSING ALTOGETHER etc.
To summarize, we are just laughing at how Goblet of Fire is arguably the worst and most different movie in the movie series.
