Homer "A trillion dollar bill? Wooooow. That must be worth a fortune
And because no one else has posted it yet...
He'll sting you with his dreams of power and wealth!
Beware of Scorpio!
His twisted twin obsessions are his plot to rule the world
And his employees' health!

But beware of his generous pensions
Plus three weeks paid vacation each year!
And on Fridays the lunchroom serves hot dogs and burgers and beers!
He loves German beer!
