Never drink cooking oil...

Ladies & gents, let me tell you about the time I chugged cooking oil...and regretted it bitterly. A few months ago, I went for a drink. I sew some "water" in my cup. I started chugging. But why is it so oily & fatty &bitter? And before I realized it was cooking oil, I spit the stuff out into the sink! Do you have any idea how terrible it tasted?! And no matter what I tried, I couldn't get rid of the bitter, fatty aftertaste! But seriously, as the title states, never ever drink cooking oil
