Looking back at this one now, despite having fun with it, I think I actually did pretty bad, since most accents are really not my forte...

Basically, I was trying to go for the original Wallace by Peter Sallis, since the commercial being dubbed here was voiced by the new voice actor for Wallace, Ben Whitehead. I kinda lost it somewhere near the end, but I tried to make it sound legit....if that's the right word.
And here's the original ad if you want to compare: http://www.youtube.com/watch?v=KY_3NQWovCY
