Men fixing broken things!! light switches, toasters, clogged toilets it's a tradition that dates back to, well, a time when men did things besides sit on the couch watching football with their hands down their pants. We know that you probably can't gap your points or replace the alternator in your love wagon. But with a little practice, and some very basic, idiot proof manuals, you can do plenty of other tasks that would establish you as a Competent Male and one sexy Mo Fo! there's nothing better than seeing you with a sexy tool belt and just a little bit of manly work going on around the house.
If you're going to do this, though, try to do it in her presence obviously you want her to see you looking manly with your "tools". And it's okay, even advisable, to cuss if you can't find the right tools, as long as you don't complain.
Warning!: Do not get dirt on your face unless you're doing something fairly complicated. There is a thin line between looking manly and then looking like we found you under a bridge.
