50 Cent is easing into it at level one.  Whereas  Boosie is out there paying folks 4K to climb up difficult stacks of crates.

Here are some of the results, including one woman who fell right on her head and YK Osiris taking quite a tumble.

"I almost had the 4,000," Osiris typed.  "damn .. my back hurt like damn lol."
