Michael Trucco (as an experimental physicist), Dec. 15, 2008
The Battlestar Galactica sports-jock-turned-space-jockey plays a famed and impossibly hunky experimental physicist who begins dating Penny (Kaley Cuoco), much to the chagrin of his new research partner, Leonard (Johnny Galecki). Turns out the cad is married, and things ended up working out pretty well for Leonard and Penny after all, so, you know, the universe is fair.
