Barbie Boys
Gwen and Tosh had seen lots of things. Things that they had to remember. Like human sucking aliens and fishes oozing green slime that was deadly to touch. They were working at Torchwood so it was to be expected.
And they'd also seen a lot of things that they really didn't want to remember.
Jack and Owen, wearing Barbie shorts, blonde wigs, hot pink dresses and singing their own made up version of I'm a Barbie 'Boy' while Ianto danced around them with a garland of flowers round his neck and playing a ukulele was one of them.
