threesome with two Cybermen, a race of cyborgs from Doctor Who. Satirical technology columnist Verity Stob wrote a parody of Torchwood Season One in the style of Dylan Thomas's radio play Under Milk Wood, called Under Torch Wood. This parody described Captain Jack as "the insomniac bicon; snug as a hobbit, pretty as a choirboy, immortal as carbon dioxide, wooden as a horse." Barrowman's ubiquity, however, has even provoked criticism of the character. Jim Shelley of the Daily Mirror, in his review of Children of Earth, said "Unlike David Tennant's Doctor, Barrowman's endless appearances on friendly drivel like Tonight's the Night, The Kids Are All Right and Any Dream Will Do, is so over-exposed, 'Captain Jack' is about as intriguing or alien as a Weetabix and twice as irritating.

"Harkness is of course a man of mystery. You can't tell what he's thinking just by looking at his face... no matter how hard Barrowman tries." The character's recognisability extends outside the UK. In a Halloween episode of the 2008 series of American drama Knight Rider, character Billy Morgan (Paul Campbell) dresses up as Captain Jack, whom he refers to as "the time-travelling bisexual".

However, David Tennant appears as himself and John Barrowman is revealed as playing Captain Jack in the TARDIS set. Action figures have also been created in the actor's likeness, which Barrowman says was a "longtime dream". Starting in 2013, Jack's sexuality has made him the subject of an internet meme for discussing the ethics of sexual encounters with nonhuman characters. Known as the Harkness Test, it spread rapidly throughout the internet, where it was applied to other fandoms such as those of
