It made me smile. Not great, but definitely underr
I liked the style of the graphics - nice lines and shapes. Fonts were cool too.
My one criticism is the key, which looks like it's pointing behind him - it doesn't look like it's at an angle with the end where it's meant to be.
The 'b' made me smile, as did the actualisation of the product.
However, it just wasn't enough to get me laughing. At the end, I had the 'eh, is that it?' feeling. 2 problems - sudden end and not as funny as it could be. Maybe even ending with some big flashy letters on star shapes when you're talking about the pricing and tel. # would help with the former. Maybe taking it to more ridiculous heights, maybe showing it being used publicly, would help with the latter.
