And now, the TV show's fans got to see a sneak peek of what Miley's character is about in a clip in which she is introduced to Jon Cryer.She introduces her self as "... Missi. Everyone thinks it's short for Melissa, but it's actually short for Mississippi -- the river, not the state," before she goes on a TMI trip in which she recounts how she was stung by a jellyfish and had to have a friend urinate on her leg.

Britney Spears on How I Met Your Mother: Pop sensation Britney Spears made a couple of appearances on How I Met Your Mother as Abby, the secretary to Stella (Sarah Chalke), who is Ted's love interest.
