1. Do not watch The Grudge 1, 2 and 3 in one night. Holy fucking shit. 2. Do not put two camels in a tiny car.
and if you do both at the same time?
I'd say: try it.
do not watch the butterfly effect and donnie darko late at night leaving your flat door open, allowing a guy to come in and start shouting "don't be disillusioned!" repeatedly.
Another: have sex in public areas.
I made two camels watch the Grudge 1, 2, and 3 while in a car.
