The Catherine Tate & David Tennant sketch from Comic Relief Tennant plays substitute teacher Mr. Logan, who goes head to head with Tate’s 'Lauren Cooper'. Absolutely hilarious, this one never gets old! (from Geek Chic ~JB pop-Eggs)
Doctor Who Challenge Day "Your Favorite Doctor": I like the Doctor. But my favourite actor to ever PORTRAY the Doctor is David Tennant. His dedication and love for the series is extremely admirable and I love the quirkiness he brought to the role.
