 A line spoken by the Doctor, "The angels have the phone box", is rhetorically repeated by Larry and prompts him to say "I 've got that on a T-shirt". As expected by Moffat and Gold, this led online retailers such as ThinkGeek, and Zazzle, among others, to offer versions of such a product for sale. In addition, the "wibbly-wobbly timey-wimey" line has been used to describe several of Moffat's complex time travel stories, such as "Let's Kill Hitler" and "The Big Bang". The line was also referenced in the first episode of the fifth series, "The Eleventh Hour", when the Eleventh Doctor (Matt Smith) scans the crack in young Amelia Pond's (Caitlin Blackwood) wall with his sonic screwdriver. BBC America created a series of four specials prior to the seventh series premiere of Doctor Who, including one entitled "The Timey-Wimey Stuff of Doctor Who".
