As ratscloset said, it's hard to say why your object looks "funny" when you don't say in what way you think it looks funny, and do not provide us with any clue as to what it should look like. If it looks a different shape in the rendered image than it did in the preview, then the culprit is probably smoothing, try turning 'Smooth Polygons' off in the objects Properties. If that does not help, show us, or tell us what it is supposed to look like.
