why r smurfs blue? y r they called apart-ments when they're stuck together? what would chairs look like if our knees bent the other way? y do people always press harder on the tv remote even when they know the batteries have run out? if a petrol station is open 24 hrs a day 365 days a year y r there locks on the door?! y is there always 1 jaffa cake facing the other way to all the others in a pack?!!
