I hadnt heard that, I liked him in Torchwood-more gritty than Dr Who. Heard he did it on set, but not seen him interviewed. Which one are you on about?
On November 30, 2008, Barrowman was asked during Radio 1's Switch programme about his habit of exposing himself during interviews, and did so on this occasion. Although the act was not seen (a show staff member had covered the webcam), the BBC and Barrowman subsequently apologised for any offence caused.
