The Pirates... The Orioles should have mashed them back in '71 and '79.
Besides, most Pirates fans are also Steelers fans, and we all know how obnoxious they are!
Thank goodness they don't play each other very often... Don't even like them playing each other in preseason.
Not a fan of interleague play... It was a nice change when it first started, but the novelty has worn off.
