Triple rainbows do exist in theory but generally they are too dim to see without image enhancement

[David Cooper]

The weather conditions in Aberdeen frequently produce triple rainbows which are very clear to the eye, though I don't think I've ever seen three full arcs - usually it's just the lower ends of one side of a rainbow against thudding black cloud. It came as a big surprise to me to hear that science was questioning their existence. I don't think I've never seen a quadruple one though.

Does holding a car remote to your head make it work better?

The radio remote at temple increasing range has been discussed before : you are a better antenna for the transmitter if you hold the the remote control near your head  ...

When a transmitter is connected to an antenna by a feed line, the impedance of the antenna and feed line must match exactly for maximum energy transfer from the feed line to the antenna to be possible. The impedance of the antenna varies based on many factors including: the antenna's natural resonance at the frequency being transmitted, the antenna's height above the ground
