I’m sure there’s a joke to be made, but I’ll leave it to others to make it.
That Chuck Norris is a bad mother…
It’s also Osama bin Laden’s birthday, oddly enough.
Chuck Norris built the hospital he was born in.
I pray that Chuck is having himself a safe and awesome 73rd birthday! 
God bless you and him always!!!

Hush your mouth.
Chuck Norris doesn’t have birthdays. He just roundhouse kicked the sun 73 times.

What would be your motivation for noting the birthday of Norris?
Staying alive.
Sadly, roundkicking his own brain seems to be taking it’s toll.
I’m sure he’s personally a nice guy, but he’s an epic teabagger moron.
On the other hand, missile launcher motorcycle.
May he live to see every one of the coming thousand years of darkness.
But I’m talking about Chuck Norris
He can break things with his hip!
Then we can dig it.
Who’s the cat when things get weird
Beats up bad guys with his beard
Chuck!
Right on
