Oh, come now. Bodybuilders (and other strict dieters) sometimes do drink oil (olive oi etc.l) to get good fats. Tastes vile, though.

At first I thought "oh, God, why?" then I remembered that I once had to drink 12 oz of oil to help out my gallbladder... So it's a legit sentence assuming der Mann has stomach problems.

True fact: in swedish ÖL means beer!

Here's a bloke drinking oil. Happy now?
