New Theories…?

2nd RunnerUp
The ‘Why Yawning Is Contagious’ Theory: You yawn to equalize the pressure on your eardrums. This pressure change outside your eardrums unbalances other people’s ear pressures, so they must yawn to even it all out.

If an infinite number of rednecks riding in an infinite number of pickup trucks fire an infinite number of shotgun rounds at an infinite number of highway signs, they will eventually produce all the world’s great literary works in Braille.
HONORABLE MENTION:
The quantity of consonants in the English language is absolutely constant. If consonants are omitted in one geographic area, they turn up in another. When a Bostonian “pahks” his “cah”, the lost r’s migrate southwest, causing a Texan to “warsh” his car and invest in “erl wells.”
THE GRAND PRIZE WINNER:
When a cat is dropped, it ALWAYS lands on its feet; and when toast is dropped, it ALWAYS lands with the buttered side down. Therefore, I propose to strap buttered toast to the back of a cat. When dropped, the two will hover, spinning inches above the ground, probably into eternity. A “buttered-cat array” could replace pneumatic tires on cars and trucks, and “giant buttered-cat arrays” could easily allow a high-speed monorail to link between New York with Chicago.
