<human>: OK, I'll go first.

When I was at uni, in my accommodation there was one toilet & kitchen between two people in each mini flat and my flat mate was visiting his family over reading week. After a night of drinking and eating curry, when I got home I just about made it to the toilet and proceeded to have the biggest dump I can remember before passing out in my room, half mast after trying to have a drunken wank.

Next day comes around and to my horror I hadn't flushed the toilet, so I did the good thing and hit the flush. The problem was that this dump was so big it just wouldn't go down and their was a fair bit of toilet paper in there too. After the water rose and slowly subsided hiding most of my droppings beyond the U but still being able to flush completely, I hatched a plan so that I didn't have to call out maintenance guy. I baked some laxative cookies for my room mate and left them on the table with a note for him to help himself and that I'd be back later.

Long story short, he evacuated his bowls into the blocked toilet and after flushing a few too many times causing the befouled water to spill out onto the floor had to clean up the mess and call maintenance to fix the toilet. I never told him.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I blocked the toilet but gave my flatmate laxative cookies so that he'd think he was the one who blocked the toilet.
