Take a gander at this!  Not only will they clean your dryer vent, if you own any ducks, they will clean them too!  I wonder how many ducks they will clean for the one price.  I guess we could wait to see the bill (get it?). 

Now, I know that all too many people pronounce the word 'duct' as 'duck'.  In fact, one popular brand of duct tape calls itself 'Duck Tape'.  (Why would anyone need to tape up their ducks?  Does it keep them from flying away?)  I actually did not know if this was done on purpose or not... at least until they changed the sign a few days later with the one below.  I tell you, it's enough to drive one quackers.
