simple header / footer theme?

All of the themes I can download look nice and all, but I really need to incorporate my website's HTML header and footer like I've done with the other scripts I installed on this site. I don't want to tweak anything just yet - is there a really simple theme that has a header/footer file I could change? Changing the theme.tpl to include the header and footer seemed to cause weird problems - I guess I'll debug them eventually but I don't really want to have to deal with it when all I need is a header/footer thanks!
