A combination of the "Houdini" and the "Jelly Donut". While having intercourse in the "doggy style" position, you spit on your partners back just before blowing your load. This fools her into thinking you have ejaculated, she turns around, you ejaculate on her face and punch her in the nose. The semen and the blood mix into a jelly sauce. (If your lucky she will eat it, afterall breakfast is the most important meal of the day!)

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
