Two points:Even if they stick to celebrities or reality tv or stuff going on online, It feels like there could be a lot more they could use for the show.
Disney does NOT own everything (yet lol) sometimes it feels like Bill and Ted don't have enough things to make fun of, but there were so many other things they could have mocked.
like for example, when old Han Solo came out, Terminator should have come out with a walker as well. or something. Sarah Connor could have been used. have Sarah have a conversation with the Star wars girl about getting Terminator into the star wars home or something... I don't know.
every year it feels like they have less things to make fun of, yet there are so many things going on every year that they could use that are not Disney related.
What if they just stayed away from Disney stuff and just make fun of everything else?
(1) Non-Disney companies can be equally protective of their IPs. Made even more awkward when they're your business partner. Remember, Avatar jokes only started after Disney secured the rights--initially, Universal was trying to win that IP (supposedly to replace T2), so the alien blue cat people were verbotten.
(2) Crowd is overwhelmingly local, writers can be expected to play to that a little. Why we get Morgan & Morgan jokes, and why such a heavy emphasis on making fun of Disney. I'd wager the majority of people in any given audience work for the Mouse or have been to WDW in the past year.
