Help! We're having terrible trouble uncurling our toes after watching this hilarious-but-so-embarrassing sketch from the second series of Important Things With Demetri Martin.
Just watch it and you'll see what we mean. The thing is... this kind of mix-up could so easily happen, couldn't it? And we have a terrible feeling we'd behave in much the same way.
You know, it kind of reminds us of the time that poor fella got roped into appearing as an expert on BBC News 24 when he was simply waiting to be called to an interview for an IT job. Shudder.
Anyway, don't uncurl your toes just yet, folks. It's time to look at some more embarrassing fails...
