Like a kangaroo

Proofread this snippet

Yesterday at lunch, Albert Sandy was telling everyone about this guy in China or Thailand or someplace who could jump six feet straight up in the air, no joke. The way the guy did it was by digging a hole that was three inches deep and then jumping in and out of it a hundred times. The next day, the guy doubled the size of the hole, and he jumped in and out of THAT. By the fifth day, he was practically like a kangaroo.
