Someone stole the catalytic converter from under my housemate's truck. They cut it right out. Both pipe-ends are perfectly round, so it wasn't sheared. They probably used a sawzall, but I can't figure out how they did it without waking up the whole neighborhood.
Freakin' thieves, man. Criminals make me angry for different reasons. With thieves, it's because the rest of us have to work for a living, and they just get to kick in doors and take from you.
