A guy was telling his friend about his recent hunting trip to Alaska.
"We were out in the woods all morning and our guide decided that we should take a break along the river bank. I wasn't feeling tired so I went for a stroll while the others were resting.
As I was walking, a grizzly bear burst out of the undergrowth in front of me. I turned and started running like hell through the woods with the bear after me. The bear almost caught up with me but slipped and fell down. I kept running and the bear almost caught up with me again twice, but slipped and fell each time. I finally reached the river bank. The guide saw the bear chasing me and shot it dead."
"Wow!" replied his friend, "That's incredible. If I were you, I would have chit myself."
The first guy answered, "What do you think the bear was slipping on?"
