No way, it was totally Teodor's fault. he blew up first, he was the one slamming Beef's family, and after all, whose wedding is it anyway? Not Teodor's.
I am defending the honor of a talking cat in his argument with an alive stuffed animal. It is time to stick my head in the oven.
That doesn't make Beef any less an ungrateful jerkass. He and Teodor are, as we're discovering, two of a kind; it's just that Teodor puts on the brave front while Beef wears it on his sleeve. Beef fucked up be refusing to be grateful for a good friend's best efforts, even if it wasn't his sort of thing.
And let's see where that leaves him -- Ray, who is hosting and is sort of oblivious; Lyle, who couldn't care less; Philippe, who is way, way too young; Pat, who would have to top for Rod even if Rod wasn't a bottom because he's already got a pole shoved up his ass; Todd, who nobody ever wants around anyway; and Nice Pete, who is of low mind (infernally so). And we already know Cornelius, Emeril, and Spongebath won't be there for whatever reason. No, unless Ramses Luther and Ghost O' Molly's Dad can show Beef a good time like he's never seen, Beef's SOL. And evidently that hasn't come to pass, as we see in the last panels.
