From Fark, I learned that researchers have discovered clues as to why yawning is contagious.

Self-aware or empathetic people are more likely to catch the yawns, say US researchers.

Contagious yawning is known to be more than coincidence. Studies have shown that 40-60% of people who watch videos or hear talk about yawning end up joining in.

Fascinating stuff. I think I yawned four times just writing this!
