One day, when Alfred's hamburgers were being particularly annoying...
"Alfred, do you consider a hamburger to be a type of sandwich?"
"Yeah, the best kind."
"You do know that sandwiches originated in England, right?"
"..."
"Well?"
"We Americans made it better, like everything else of yours."
"Oh just shut up."

AN: Not necessarily true, but England wanted to freak America out. Sadly, it didn't work.
