And we aren't only talking about secret service agents. Of course amphibious cars are nothing new. The first military application of water-going vehicles dates back to the 1930s while civilian amphibians have been around since the swinging 1960s.

The 21 Best

Here at the Conspiracy section of truTV.com, we like to be at the cutting edge of what theories are out there.

One way we do that is with our Tipline, wherein we encourage you, the public, to submit conspiracy theories you think we should investigate. While we aren't able to follow up on every tip (and where does on start with a theory that says simply "JFK was murdered," for example?), we do get many interesting ones that we wish we could explore further. These, we feel, are the best of the best.

Although they have been edited for length and content, each tip retains the original intent of the submission from a real reader. As always, keep the suggestions coming, and remember that the only dumb question is the one that isn't asked.

 You’ve never seen nails like these!
