How I Met Your Mother: 10 Most Embarrassing Moments

9. Revertigo

There's nothing quite like a white person making an urban impression to make you feel incredibly awkward and Lily's transformation when her old high school friend Michelle turns up is up there with the worst. The episode Sandcastles In The Sand and is full of embarrassing moments - Barney gets his Robin Sparkles experience in the form of her rather arty follow up single to Let's Go To The Mall. The episode looks at how the group change when around people from their past and to prove his theory of "revertigo", Marshall calls up Michelle. In combination, Lily and Michelle spout all sorts of urbanism like "gurls" and "true dat", replete with swagger-ful walks. In an episode based around taking the mick out of most of the characters, this ridiculous moment certainly stands out.
