[sblock=The Joke]Finding Forrester is a movie about an aspiring African American writer who attempts to balance his dream with his troubled life among the inner city urban landscape. He finds an unlikely mentor in the character played by Sean Connery (a famous Scottish actor) who is a well known, but extremely reclusive author (Last name: Forrester). The young writer pushes against Forrester's initial reticence and eventually strikes up a friendship over their common love of writing.
At one point in the movie, Sean Connery's character congratulates the young man, and in an effort to emulate the urban slang of the street kids, declares that,
"You're the man now, dog!"
For whatever reason, this phrase, uttered by Sean Connery, inspired a web phenomenom by which an image or small clip from the movie was tiled over and over again on a webpage along with the sound byte on a continuous loop. See
Wikipedia for further information on this phenomenon.
Teen Wolf (and Teen Wolf Too) are movies from the 80's, the initial starring Michael J. Fox (a well known young actor of the time, now disabled with Parkinson's Disease). The basic premise of the films is that a young highschool student (a teen, if you will) gets bitten by a werewolf, and contracts lycanthropy. Thus becoming a wolf (a member of the canid family, thus related to a dog) under the full moon.
The humorous juxtaposition of these two movies produces a young, teenaged writer who contracts lycanthropy, inspiring his mentor to declare that,
"you're the dog now, man!"
A witty twist on the original phrase uttered by Sean Connery.[/sblock]
