Insane Charlie Sheen quotes in honor of his 50th bday

Remember how yesterday we were talking about how Keanu Reeves looks the same at 51 as he did in his 20s?

Well, here's one birthday boy you can't really say that about: Charlie Sheen, who turns 50 today.

Here he is in 1986 in 'Ferris Bueller's Day Off'

But it's not like he hasn't enjoyed those 50 years to the fullest, especially when he spent most of 2011 telling us how awesome he is.

A Sheen sampling:

Coming to terms with who he REALLY is

What will happen if you come at him

OR HIS FAMILY

ABOUT THOSE PESKY DRUG RUMORS ...

ACTUALLY, HE TAKES THAT BACK ...

HIS GENETIC MAKEUP IS LIKE, TOTALLY DIFFERENT
