To be honest...
This isn't as funny as the last two. I know that changing a good formula that's worked over the years in bad, but it is getting a bit old.
However, you note that during the flash with Charlie's dialogue so at least your aware of it.
Some parts did make me laugh but it was the ending that did catch me off guard and got me laughing for about a minute.
Trying mixing it up a bit next one?
