Poseidon's Pillow 

How one defeats Psoeidon's Kiss:
Placing a couple sheets of fresh toilet paper in the bowl before a sizable bowel movement, reduces the risk of Poseidon's Kiss.

Aww man! Poseidon's Kiss again?

Next time try using Poseidon's Pillow!

Hey, who the fuck are you and what is Poseidon's Pillow?

Neverfuckingmind who I am. Poseidon's Pillow is where you simply place a few sheets of toilet paper in the bowl before you take a giant shit.

Oh, sounds cool.

Spillover Perks

Spillonomics 

1. A scientific way to calculate the true costs of massive oil spills, such as the BP Deepwater Horizon disaster in the Gulf of Mexico.

Spillonomics was conceived shortly after the 1989 Exxon Valdez spill in Prince William Sound, Alaska. Sadly, it has become a major growth industry in the last 21 years.

Unlike other methods favored by the petroleum industry, Spillonomics takes into account both short-term clean-up costs AND long-term costs related to marine ecosystems, tourism, fishing, coastal employment, real estate values and water quality.

2. Dick Cheney's latest nightmare.

I'm majoring in Spillonomics. My uncle at Halliburton is livid. Serves him right!
