In 2005, Galecki played Mark Corrigan in a pilot for a US adaptation of the British sitcom "Peep Show". He played a character named Trouty on TBS's sitcom "My Boys", and the half-brother of the main characters, sisters Hope Shanowski and Faith Fairfield, in the sitcom "Hope & Faith". Galecki originated the role of Alex, a male prostitute, in the play "The Little Dog Laughed" by Douglas Carter Beane, in 2006 at Second Stage Theater. He stayed in the role for the play's Broadway run at the Cort Theatre in late 2006 and early 2007. Galecki said at the time, "At its core, the play is about what we all sacrifice to be successful, whatever our careers or goals." The play was a commercial and critical success, and Galecki won a 2007 Theater World Award for his performance.
