When Verizon Thunderbolt's Wall Charger Is Not Enough?

Here is a new ad from Verizon for their new Thunderbolt phone:

The fine print was very early in the ad:

While “Do not attempt” is one of the most common fine prints in ads, this one is strange because who would even attempt this? What is he even attempting? Harnessing lightning? I would only trust Doc from Back to the Future to do that. I am actually more concerned about walking across rooftops with a ladder. I do not think Verizon has to worry about lawsuits from people walking across rooftops with long power cords in order to power their phone.

Thanks to reader Michael Mills for the idea submission.
