Mechanical bull
The commercial use of mechanical bulls gained popular appeal with the release of the 1980 movie Urban Cowboy.  In this movie John Travolta and Debra Winger showed the riding a mechanical bull.  The mechanical bull used in this movie was the El Toro brand of mechanical bull.  This brand of mechanical bull is still being made, but does not carry the same safety features that are available on more current models. Mechanical bulls can also be seen in the films Stir Crazy, and Charlie's Angels: Full Throttle. In the movie Barnyard, in the night barn, a "Mechanical Man" is seen (as the main characters are cows).
