1) A major part of the carbon cycle that has helped properly regulate the temperatures of earth and the CO2 levels within earth's atmosphere for quite some time and won't just break because a few humans start driving SUVs and cooking on charcoal grills.

2) The confounded and/or irritated look on someone's face when you tell that "What color is a purple house?" "Purple" "What color is a blue house?" "Blue" "What color is a green house?" "Green" "WRONG! It's clear!" joke, because green houses are actually quite green, and they hate you for telling such a stupid joke.

While inside the first set of doors in the double door greenhouse entrance of fast food restaurants, one person stands inside with both doors closed and releases flatulence while shaking their body, then immediately enter the second set of doors and closing the door behind them as fast as possible.

When a man that has been blessed by the nutrients of sun and is at full capacity of ejaculation, he then begins to photosynthesize (this may take a few minutes). When the process of photosynthesis is complete he then releases his seed directly in the woman's mouth, then butt and finally finishing with the vagina (aka The Gut). The woman is then to take care of his seeds and supply them with nutrients and plenty Vitamin D for the rest of her life.

The sex act in which the Green Bay 'resident' inflates a plastic bag over their body and proceeds to be urinated on by any number of partners playing 'mother nature.' The effect is the warm feeling that Midwesterners get by being in a greenhouse during a gentle summer shower.
Wow Steve, we're gonna need a mop to clean up this Green Bay Greenhouse before your wife gets home.
