Victim Number 8 Puns

Carl had this calling card of his. When he was nearly done burgling a house, he would put a brick inside the victim's washing machine, and switch it on. The washing machine would destroy itself, and the owners would know that the perpetrator could only be Carl.

Carl's number eventually came up, when he burgled a house with three savage guard dogs. They put an end to his burglary career.

I guess you could say, washing machines live longer with Carl gone.
