Basically, the first translation is "I'm Angel. I'm a loser." and the second, "I didn't clean the room of the loser." I've always wanted to know what it was that they put on Angel's door and now that I know I want to share it with y'all. That's a highly intellectual prank (I think that's what they called it) right there.
Merlin: "Arthur won't even notice I'm gone" Arthur: *spends entire episode wondering where he is and demanding him at his side*<<<thats because he's incapable of functioning without merlin<<<For real. He couldn't even put in his own shirt and had to have Guias help him!
