You find yourself repeating the same formula over and over, don't repeat the same formula over and over

I personally love stuff that is funny because of the fact that it makes no sense. It's risky for a company to use this kind because you run the risk of being misconstrued. Besides that, there is always the chance of getting predictable. As random as they are, this is still what DIRECTV's  'Get rid of cable' does. The first one you watch is the best, after that they deteriorate fast.

The one with Charlie Sheen is probably the best, so we'll start with that.

Here you go, from recording conflicts to re-enacting scenes from Platoon with Charlie Sheen in just five steps. That was funny, right? Even though the choices are pretty far fetched every single time, the commercial gets old after five times. The formula is simply too easily copy-pasted onto another ad. The formula itself is nothing more than:

0:00 - 0:02 | 'Here is a problem with cable tv'
0:03 - 0:26 | 'Let's extrapolate and use hyperboles to get to a ridiculous situation'
0:27 - 0:30 | 'We're so much more awesome buy our stuff!'

Let's talk DIRECTV through this process in a way they might understand.

When you repeat the same joke over and over

again in your commercials, it gets boring.

When it gets boring, your customers will

start browsing the web for entertainment.

When your customers start browsing the 

web for entertainment, they might find

funnier stuff than what you're offering

When your costumers find funnier stuff

than whatever you're offering, you'll lose profit.

When you lose profit, you might go bankrupt.

When you go bankrupt, your CEO's might

have to live in a box. Don't let your CEO's live in a box.

All I need is Robb Webb to voice it, it's a wrap!
