But what will they call it?

It's been all over the news that Burger King is buying Canadian breakfast and lunch giant Tim Hortons, so that they can move the corporate HQ to Canada and enjoy a lower tax rate.  All that is well and good.  But the problem is, what will they name the new chain so as to maintain corporate name recognition?

"Burger Hortons"? 
"Tim "the King" Hortons" 
"Burger, Coffee, and a Donut King"?
"Tim King"?

Well, I doubt they'll change the name of either one, though the menus of both may get enhanced.  But I'm sure some comedians will think the way I'm thinking.

Burger King, Tim Hortons merge into a whopper-size firm

Ohhh, that was a good one.
