You don't often run a cross a really funny commercial.  They're usually mildly amusing or predictable or just plain dumb.  These are different.

I had a hard time picking a favorite of these 15.  I'd probably narrow it down to the wildly accident-prone guy or the anti-theft car system or the trucker helping the jogger or...oh, who am I kidding, I laughed at all of them.

See if you can find a favorite among these 15 funniest commercials of all time.
