He crashes on your couch when he loses his job

A guy pulls a knife, and you jump in front

You take the blade right in the gut

Ow! Then he holds your hand till the medic comes

You feed him soup when he breaks his jaw

You help him pee when he has that thing

He's your best friend

He crashes on your couch when he loses his job

He helps you pee when you've got that thing

Your best friend
