Secret Agent X-9

Got a racecar grin and a calculation
And every gun for a secret agent
Defunct that timebomb at the space station
Hey, Secret Agent X-9, why don't you drop me a line?
And say, would it cost you your job
To say what was in that gold box?
So why did they give you that job?
And why can they give you that job?
You'd think this guy was on a permanent vacation
But no, he's not, he's a secret agent
