This is one of my new favourites!
There were moments that had me actually laughing out loud and I was in a really crappy mood so it wasn't just that I was feeling silly and anything would have made me laugh. It was hard to decide what was funnier - the riffing, or the fact that this thing existed at all to begin with.
I loved the dialogue with the "eggstraordinary" creator Ronald Underwood where he's being fired by his client: "We wanted something for kids about courtesy...and this is just a buncha crap about eggs..."
Then the part where all three riffsters go ape in front of the "egg-firmary" and all just start chanting "Eggy-eggy-eggy". I seriously nearly had a food accident over that one (nope, not eggs. Too bad.)
Benedict's brain damaged self was pretty funny too even though it was creepy - not icky-creepy, more like goofy-creepy.
I give this an A+ (egg-plus?)
