My standard joke has been that everything with a power chord or a battery is my problem, except for the lights, but that doesn't even cover it. I've done everything from making sure there's equipment for the entertainment during our conferences, to making custom computer screen mounts for the benches in the lab, running ethernet cable in the office, setting up and installing temperature monitoring equipment for climate controlled incubators, editing promotional videos, taking product photos, helping the web team build sites, recording voiceover, and a whole lot motre. I even fixed the damn lights for the office Christmas tree. And all that is in addition to the normal IT stuff. In a smaller company, if you're the IT guy, they will probably turn to you with anything remotely technical.
