Btw, I became curious about the origin of the term "hot dog" after your comment and found the explanation here, so I pass it along as a useless piece of trivia :)

Vendors were hawking hot dogs from portable hot water tanks shouting "They're red hot! Get your dachshund sausages while they're red hot!" A New York Journal sports cartoonist, Tad Dorgan, observed the scene and hastily drew a cartoon of barking dachshund sausages nestled warmly in rolls. Not sure how to spell "dachshund" he simply wrote "hot dog!" The cartoon is said to have been a sensation, thus coining the term "hot dog."
