There was this odd tip on facebook that said putting a car or tv remote under your chin and opening your mouth will extend its range. Is that true, and why? Am I gullible?

You could try it and let us know what you find  [;D]

Most TV remotes use IR, and require direct line of sight between the transmitter and receiver. 

I find it doubtful that your chin trick will do much.  However, gaining elevation over using it at lap level may help a bit if there are potential obstructions.

Presumably the LED could be focused better to extend range, but that would also require one to point it directly at the receiver.

Extending the range of a car unlocking remote control by holding in a certain position works because of at the relatively long wave length at which these devices work (about 0.6m ) configuring the body in certain ways make it act as an improved antenna.
Remote controls for TV,s etc Work in the infra red range about 1 micro meter so such considerations are not relevant

It might work over twice the usual distance if you have a double chin.

............ Am I gullible?

I have developed a sure fire way to tell if someone is gullible.
