A staged wedding to bust dealers
As supposedly reported on CNN:

Undercover police, staging the wedding of "a drug kingpin's daughter", let it be known on the street that dealers were "invited" (i. e. Expected to attend).

The bride and groom were police, as was the band, bartender, and about half the guests. The band playing at the wedding was "S. P. O. C." (COPS, backwards), and the wedding went through the full ceremony, including the dancing afterward.

The long-sought dealers were arrested after the "band" took their break. The last song the band played before taking its break? "I Fought The Law, And The Law Won"

Anniversary Flowers
A sad-faced Doug walked into a flower shop early one morning.

The clerk was ready to take his order for a funeral piece, based on the look on Doug's face, but soon realized his assumption was wrong as Doug asked for a basket of flowers sent to his wife for their anniversary.

"And what day will that be?" the clerk asked.

Glumly he replied, "Yesterday".
