Contest was submitting an idea for Evil Bong 3. A friend and I came up with this...
Evil Bong 3: Wrath of Bong
The film opens in space, with an asteroid hurtling towards the Earth. Upon closer inspection, there's some strange glowing grass attached to the asteroid. The grass pulses. It's alien marijuana. The asteroid crashes on the Earth not far from the new home of our favorite stoners. A homeless guy comes across the grass and realizes a strange alien pipe -- an Evil Alien Bong -- is inside the asteroid. The man smokes the alien weed. Except it's not like normal weed. It transports you to an alien bong world, filled with scantily clad (preferably nude, obviously) alien babes and the Evil Alien Bong. The alien weed is able to clone itself and slowly begins creeping around the neighborhood. Soon, more and more people are being transported to the alien bong world. It's a full-fledged alien stoner invasion! Our stoners know the only way to combat the Evil Alien Bong threat is with something they'd pledged to forget: Evil Bong. Only the Earth's own Evil Bong is powerful enough to defeat Evil Alien Bong. The four must bring the Evil Bong with them into the alien bong world and defeat the extraterrestrial menace within its own world. Once defeated, they have sex with the aliens. Naturally.
