One of my favorite films is the mockumentary "This is Spinal Tap."
In one scene, Nigel Tufnel (Christopher Guest) shows off the one of the band's guitar amplifiers, the settings of which go up to 11, saying, "Look, right across the board, eleven, eleven, eleven."
This is the source of the phrase "turning it up to eleven."
Here's wishing everyone a weekend that's one more than a 10.
