TTN is something I think Barrowman cooked up himself; it's part variety show, part wish-granting. People write in an nominate friends or family to have a special wish granted (usually to do with performance) and then Barrowman makes it come true. Like, that episode a woman did a duet with Dionne Warwick, a teenager got to dance with his favourite dance troupe (that's him LOLing at Barrowman on the right), and two sisters got to perform on the show as the witches from Wicked. Barrowman does stunts and talks to the audience and hosts it and all.
