Beat em off: The bleeping of the cursing is weird and if I tried to prank call a friend they'd know something was up, so I'd never use that one.
I'm a boss: The end when he says boss is cut too soon.
FU you criminal: at the very end it cuts and makes a sound. I wouldn't use that one either.
Friends: End is cut too soon. Ends abruptly, so it sounds weird.
FU: too much echo or background noise.
F*cuk Youself: Is cut to soon, and ends abruptly as well.
out of your minds: same as most of the above reasons.
But overall, great job, keep it up.
