Let us consider the facts regarding Sir Ian, and what makes him so kick ass:

1. He played, and will play again, Magneto, the Marvel comics super villian, who, if he wanted, could use his powers to sends tacks through your nuts if you were bothering him.

2. He is playing Gandalf, the best wizard ever in The Lord of the Rings movies. Therefore he could turn that small cock of yours into a vagina if he so pleased. If you're a girl he could ummmm turn your boobs into ahhhhh...... non...boobs or something.

3. He has been knighted which means when called upon by the queen he has to suit up and fight evil with his lance and sword. He would then be called by his Knight name: Sir Gonnasmokeyourass A Lot.

Now all you Star Wars fans are probably saying to yourself: "Well shit man, Sir Alec Guinness is way more of a kick ass old man than Ian McKellen, he was fucking Obi Wan and shit, plus he's a Knight too, even a Jedi fucking Knight." Well, that's a valid point indeed, Alec Guinness is quite "boss" in his rights (God rest his soul) but he is only problem was that HE DIDN'T LIKE STAR WARS. So that puts him just behind Sir Ian in the best Old Man in the world category. I bet you Sir Ian watches X-Men at least twice a day saying, "My I kicked a lot of balls in that movie."

When Sir Ian isn't busy doing harmful things to your gonads, he's out on the town and such, womanizing and proving to all of us that some old timers still got it.
