Ain't it obvious? Spongebob isn't gay! The show had all those gags going on because they wanted to get a reaction from the audience and maybe they wanted to wind up the guy who started the whole rumour.
No, Spongebob isn't gay! Some people think they are cool hating on Spongebob "OMG! I grew out of the gay sponge ages ago" but in reality, they are quite gullible because they are believing an inaccurate source coming randomly from a guy's mouth!
I think the people who say that Spongebob is childish need to grow up and just accept that some people actually like the show, like myself!
