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"

A Small Test
An older couple had a son, who was still living with them. The parents were a little worried, as the son was still unable to decide about his future career, so they decided to do a small test.

They took a ten-dollar bill, a bible, and a bottle of whiskey, and put them on the front hall table... then they hid, pretending they were not at home.

The father's plan was: "If our son takes the money, he will be a businessman, if he takes the bible, he will be a priest, but if he takes the bottle of whiskey, I'm afraid our son will be a drunkard."

So the parents hid in the nearby closet and waited nervously. Peeping through the keyhole they saw their son arrive. The son saw the note they had left.

Then, he took the 10-dollar bill, looked at it against the light, and slid it in his pocket.

After that, he took the bible, flicked through it, and took it.

Finally he grabbed the bottle, opened it, and took an appreciative whiff to be assured of the quality ...then he left for his room, carrying all three items.

The father slapped his forehead, and said: "Darn, it's even worse than I could ever have imagined.. " "Our son is going to be a politician!"
