It's easy to bribe the president of the US: just stay at one of his hotels and buy some thousand-dollar bottles of wine.

I once bribed Congressman Barnie Frank with a zero-dollar bill. I had the ambition of someday bribing the president that way, but I realized it was unlikely I'd ever meet the president of the US.

Now I see I could easily give the president a nonzero bribe, but I wouldn't want to.
