The boxer brownie bandit

Who pooped my pants? I ask in vain what sinful man could leave this stain? There's just no way I could cause such pain and I feel it in my gut no log's been laid but no matter how I try to wash it all away no shower in the world could cleanse my shame Who pooped my pants? Will I ever get a name? A most foul expanse that's yet to be claimed I've got mud on my hands but no one to blame On this soiled path I fear I've lost my way So head my warning As my trousers lay bare To save from mourning And for your washers care Keep an ear out for colons storming He could be anywhere
