text: their are four errors in this sentance? what are they?? 1) their should be there. 2) sentance should be sentence. 3) the question mark should be a period. 4) there are only three errors, hey, waitaminute!  but if there are four errors, then isn't the statement true, and therefore there are three errors, so the statement is false, and therefore there are four errors and my head explodes around here :(
