CBBC presenter Lauren Layfield was dressed as a clown and pied in the face. Pretty good coverage too.

I love this!

This is great!

FYI- this 'Sam and Mark' show seems to have good potential. Lyndsey Russell was pied 3 times on an episode the other week. I won't link it here as it also features minors, but it's not hard to find if you're interested.
