Who Steals a Unicycle?

Seriously.  I have (had) two unicycles.  Someone lifted one out of our garage.  We live in the most secluded arm of the complex.  It makes no sense.  How many thieves ride unicycles?  Why didn't they take my $2400 mountain bike?  If they would have taken the other unicycle, which is "nicer" I wouldn't have minded so much, but I had grown quite fond of the little cheap one.  I'm a little confused, and kind of pissed off.  I must not publish the rest of my thoughts, lest they later incriminate me for malice and forethought, should I catch the thief.
