What random command did your puppy learn?

Hey there, Just thought I'd ask : what random command did your puppy learn?

We've been crate (or small pen) training our 13 weeks puppy and he's doing pretty alright except when we're out of sight. We've been slowly increasing distance between us and him when he's in his crate. He was doing somewhat good for a day with a bit of whinge before he settles until yesterday afternoon. He had the biggest tantrum. Not hungry, no need for toilet, probably just a big fear or missing out. After some solid exhaustion of hearing him whinge for a long time I've lost my marbles (internally) and I told him with a firm voice to go sleep in my native language (been training him in English, first time he's heard my strong accent). Let me tell you he was to stunned to speak (or cry) and he actually went to sleep. I've tried it again and.. it still works. Now gotta have to teach my english speaking partner to pronounce it to perfection so he can apply that command too.
