There's been a lot, I started to write them down lol
Someone changed all pics of Ben to Carl from Jimmy neutron.
Someone changed an page an entire page into Hebrew, I don't know the page but I think it was Heatblast's page.
Then someone changed a pic to be an meme of an poorly drawn version of Widomaker from overwatch, once again I think it was Ben.
Of course there's more, These are just the ones I found funny or thought I need to remember
