I think when an ad. ,doesn't try too hard to be funny or smart then it usually is. I like the kids and animal ones in particular - both are so natural that it makes their antics genuinely funny!
On the other hand you get the adults dressing up dumb and trying to be funny, they are just a bore and I turn the sound off, or if it's really bad I turn channels - I tend to switch channels a lot!
I think the funniest commercials are the ones that bring about a reality of our lives and twist it to make it funny.
Probably situational personal relevance. When I see something portrayed and I have made the same mistake it shows me how ridiculous I probably looked.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
