Sabretooth (the non-wrestler one) and Pornstache are half-brothers - so you know their genetic line has some fantastic facial hair growth goin' on.
I mean, this sorta makes sense - especially when you look at them side-by-side, Ethan from Lost DOES kinda look like some Bizarro-Superman version of Tom Cruise. And what is the DHARMA Initiative but a magic island version of Scientology? No seriously, is it that? I really can't remember what the hell was going on with those hippie scientists.
And between Thor: The Dark World and True Blood, the world has seen both father and son buck naked more times than any father-son duo in recent memory.
Maybe you knew that Francis from Malcolm In the Middle and Hyde from That 70's Show were brothers (and weirdly both on pretty good Fox sitcoms around the same time), but did you know that Tara from The Walking Dead is their sister? If only The Walking Dead were also a late 90s/early 2000s sitcom on Fox, it would be perfect.
