similar 100% true story from a green text:

kid goes out for his 21st, and grandpa tells him that the secret to never getting too drunk is drinking some olive oil before a shot, so that the alcohol never enters the bloodstream, or something.

they follow through, and shit their pants after one round; ironically, the oil drinking did technically prevent them from getting drunk.

I don't care if it's fake, it's still a hilarious idea
