Stomach-churning footage shows how a man uses the dry skin from a blister on his foot as a secret pocket for his money.

Jam Ambrosio, 40, said he has often put paper bank notes inside the hardened blisters "for good luck."

He made the gut-wrenching trick a habit and does it every time he plays basketball with friends. The Filipino man claims that they always win the game.

Jam, from Navotas City, the Philippines, said: "Others say I'm weird, but because of this little trick, I never lose when I play basketball. I feel like I have money on my feet so it gives me an extra spring when jumping.''

Blisters are caused by shoes that fit too tightly or too loosely that rub against the skin. This is common during warm seasons among athletes, particularly runners.
