Bad Ass Bar

I don't know just how it happened, but
Somehow someone bumped into me
And I spilled my beer on this guy's shoes.
Him and his whole crew was pissed.
They were suddenly in 'ass beating' mode.
My offer to buy beers all 'round rejected
And a slick fabrication of multiple excuses
Didn't calm the situation down.  So I had
No choice but to go to the extreme with,
"Klaatu barada nikto! Klaatu barada nikto!"
His, "What'd you call me, mother fucker?" 
Was followed by the fight and getting
Kicked out of the club.  Yeah, nikto night.
