As for parlor tricks, would you believe that if you took my phone number and added the digits together it would produce the identical sum as the phone number for the Kmart in Simi Valley?

"However, mud in the sense of scandalous of defamatory charges goes back to a time well before the Civil War. In fact, this was an expression at least as long ago as 1846. So it seems most likely that the expression His name is mud was well established before Dr. Mudd met his unhappy fate."
"True. The OED lists a usage from early in the 19th century... and I wouldn't be surprised to find it had been used even earlier. The association of mud with worthlessness is obvious and natural."
