Heh heh heh....cloggs. Yeah, I have a pair but don't wear them any-more because I now have rubber ones. We call them klompen(pl.) here. One can buy bird houses made out of them these days. Yup--neat that you showed the pic...however the pun was outrageous! p.s.-- the word, "vent", is the dutch word for vendor (someone who travels about and sells things at the front door). So then, a "clogged vent" would then take on a WHOLE new meaning. --A situation where a laxative would be required rather than a brush or vacuum. -----What a language, eh?
