Would somebody please tell me what the hell is going on here? 
Sometimes you live up to your name 
Read it with a southern-type accent. Out loud helps.
M R Ducks = 'Em are Ducks.
M R Not = 'Em are not!
OSAR = Oh, yes 'ey are!
CM WANGS = See 'em wangs?
LIB, MR Ducks = 'ell I’ll be… 'Em ARE ducks!
So these three ducks walk into a bar …
I M DZ.
(I don’t do it every time, but I have been known to get into an elevator and announce, “I M N D LF8R.”)
That’s why, 'mid the hills of old Ohio, you need to add a numeral:
OSAR2
(Oh yes 'ey are, too!)
M R puppies
M Rnt puppies
OSAR2CMP
L I B M R puppies
