Jack Tripper is a fictional character on the sitcom Three's Company, which is based upon the character Robin Tripp from Man About the House created by Brian Cooke and Johnnie Mortimer.
Jack was, however, actually straight (the comedy stemming from having to "play gay" provided much of the story for the sitcom).
[4] Jack is something of a ladies' man, but is also kind-hearted, loyal, and protective of the women he lives with.
[5] In the show, Jack attended a local technical college on the G.I.
After graduating from cooking school, Jack held down odd jobs in his spare time.
