Got to drop a little math on you guys...
If you just flipped a coin 10 times (heads=home team, tails=away team), you would "hit" the parlay 1 out of every 1024 times. (2 to the 10th power number of combinations)
Assuming that the pointspreads make it a 50/50 choice (and not considering ties), you should expect that 1 out of every 1024 ten-team parlays is a winner.
