but portal is nothing more than a meme fest
they took that from mario bros, which in turn took it from "let them eat cake" THE CAKE IS A LIE!!
as in rotten food muahha
bowser ended up eating marios cake btw, so thats NOT a portal creation, though most of the community thinks it is
portal like the writers said, is nothing more than tonnnnnnnns of meme's combined.
same as bl1 bl2 etc. same writers on those.. just not blpos ahem ps i mean.
