You've never been preached to this way before.
Boston University recently released "Put Your Helmet On," a music video preaching bike safety... starring rapping puppets.
Some "educational highlights" -- in verse:
Oh yeah, you think you're so cool?
Riding like a big tool, looking like a big fool?
Rolling past reds, weaving through like a basket case?
Well I've got news: I can't see you.
I'll hit you fast and hard, whoops-a-daisy!
Speed kills, and my car hurts like crazy.
Now, watch the whole thing.
