I like Regular Show, but it feels as if you are trying to prove every single character in the show is straight; so the slash fans will get off your back. I don't know if you are actually doing this on purpose, but its obvious you know about the slash fans. The only character you haven't proven to be heterosexual yet is Pops and I will go crazy if you give Pops a love interest.
In my opinion Pops shouldn't end up with anyone. He should be off in a field somewhere looking at birds and giggling, not making out with some human chick.
Also throwing quotes in your cartoon that are anti-slash are not going to make us stop slashing them. Like making Rigby not want to hug Mordecai or get grossed out by holding hands with him. Its obvious that by doing this you are trying to get under the slash fans skin. All this is doing is making you look bad, because you are trying to punish your fans, just because you hate homosexuality in television. When really we are just carrying on with our ships, because we know its never really going to happen. Its just fun to think about it that way; no harm done.
Don't get me wrong, I am not going to stop watching your show, just because I think you are acting a tad childish. I think Regular Show is a well planned out show, that has humor that can make you fall off your chair laughing, the characters are lovable and well planned out.
