Go Mr. Obvious!!!
Do the bear one next! The bear in the crawl-space! Or the wild animal under the sink. Whichever.
Really, this was quite good. Mr. Obvious as a stick figure was much more expressive than I expected him to be, and the cartoon really didn't detract from the humour. You might put more into the idiot at the other end of the line, though...
On a sidenote, have you emailed Bob & Tom with this yet? They'd probably be pleased.
