I was with it up until...
The squirrels running up the tree tickled Murphy into a slapstick dance. At that point I realised this hadn't strayed as far from his typical fair as I had hoped. The rocket to the face and the getting high at the restaurant confirmed this.
At it's core the idea seemed refreshingly unique. I did find it incredibly frustrating how many words he could have ultimately saved if he just sat down and explained the situation fully, including a demonstration, to his wife/ co-worker right at the start of the film, and had them escort him everywhere.
Or, yaknow, he could just call in sick for a couple of days, stay in bed and sleep.
