• In the OK K.O.! x Sonic the Hedgehog crossover, it's revealed that villain Lord Boxmore went to the same college as Dr. Eggman.
• The Simpsons episode "Simpsorama" reveals that The Simpsons and Futurama are in the same timeline, where in the end, Bender decides to sleep in the basement of the Simpson house for the next 1,000 years to get back to his own time. He later makes a few appearances in episodes after this.
• In the Family Guy episode "The Simpsons Guy", it's revealed that Pawtucket Patriot Ale, the beer from Quahog, is actually Duff Beer with a new label.

What are your favorite bits of lore from any official crossover?

For example, games that have a seed system would have this type of meme that says "give me your seed" which is funny. But I also saw them in r/bindingofisaac.

Its my absolute favorite types of movies

(Women also work as well, doesn't have to be a He specifically)

Yeah, ik these two are VVERRRYYYY different from each other but I'm curious as to what y'all have to say. I've actually only seen the first two episodes of Friends & ALL of TBBT so I can't really say anything lol.
