Can I run two routers off one modem without problems?

If I were to get an Ethernet splitter/plug to basically gain an extra Ethernet port in the modem, can I plug another router into it?

I know from a networking stand point you can plug it into the other router and have it run off that, but I don't want to do that. We have roomates and they bought a router and pretend to be gods with it, constantly bogging us down when they "need it."

So we want our own with our own network and password that doesn't rely on the first router at all. I know we can go in and change the IP address and DHCP so it doesn't interfere with the first router, but will it function? Like will they constantly fight each other and make each other go offline? Or will it function as needed? Or will we need to get a whole new modem/connection?

Update:

Just to be clear, I'm talking a wifi router.

    NEVER use more than one router on the conenction. It always slows down the service, and it can cause disruption to networking or even stop it totally. you can NOT run more than one device from a modem, that os why you need to use a router to get multiple connections. You would neeed to go throught the other router and that will bottleneck ALL your devices as they will be sharing the little bit of bandwidth that is left after the other machines on the first router use most of it. You need to get a new service of your own.

    Nope, gonna need your own ISP service as Fred mentioned. So whatever service your evil roommates use (for example, cable), order one of the others: DSL, U-verse, etc.) and you'll get your own connection to an ISP.
