Clicking Sound When Pedaling

I had (still have actually) this exact problem and it turned out it was my pedals.  I was CONVINCED it was my bottom bracket and was all set to take it apart, lube it, whatever.  I can almost guarantee it's your pedals.  I have Look Keos that have a spring that flexes when I pedal, so we lubed that up and it's a lot better.  Might be a long term problem, but it helps to know that nothing is "wrong".

I had a short 'chirp' for a while...and every time I looked down to see what was chirping, the chirp would stop!  It was like the Heisenberg thing.  I finally figured it out...my shoe was occasionally brushing the crank.  When I was looking down, my foot would pivot out and it would not rub so the chirp stopped.  This drove me nuts till I figured out what it was. 

Probably not you issue though.

Knees?  Ankles? 

I had a weird clicking sound and it ended up being the end of the deraileur cable brushing against the crankarm. 

Have you tried a single-leg drill?  If it goes away, it might be the pedal that is no longer clipped.  If it gets worse, it could be the other pedal, BB, seatpost, or anything else suffering more from the additional torque of pedaling one-legged.
