Quoting rkrider2001:

For all you folks who have difficulty converting units:

Ratio of an igloo's circumference to its diameter = Eskimo Pi

2000 pounds of Chinese soup = Won ton

1 millionth of a mouthwash = 1 microscope

Time between slipping on a peel and smacking the pavement = 1
bananosecond

Weight an evangelist carries with God = 1 billigram

Time it takes to sail 220 yards at 1 nautical mile per hour =
Knotfurlong

16.5 feet in the Twilight Zone = 1 Rod Serling

Half of a large intestine = 1 semicolon

1,000,000 aches = 1 megahurtz

Basic unit of laryngitis = 1 hoarsepower

Shortest distance between two jokes = A straight line

453.6 graham crackers = 1 pound cake

1 million- microphones = 1 megaphone

=======================================
These are some... strange definitions. Read them
slowly... some may take a second or two to sink in.

EYEDROPPER: A clumsy ophthalmologist.

HEROES: What a guy in a boat does.

LEFT BANK: What the robber did when his bag was full of money.

MISTY: How golfers create divots.

PARADOX: Two physicians.

PARASITES: What you see from the top of the Eiffel Tower.

PHARMACIST: A helper on the farm.

POLARIZE: What penguins see with.

PRIMATE: Removing your spouse from the couch in front of the TV.

RELIEF: What trees do in the spring.

RUBBERNECK: What you do to relax your wife.

SELFISH: What the owner of a seafood store does.

And my favorite:

SUDAFED: Litigation brought against a government official.
