Not a prob.
Agreed the car will run like crap, but there is no permanent damage in running the car without a thermostat.
My dad had an older Mustang from the 70's, when it started to over heat he removed the thermostat. I don't think it was ever replaced till he sold the car (maybe 10yrs later)

WRONG! Iron and aluminum disapate heat at different rates. Don't believe me go right ahead, remove your thermostat, I'll start buying X type engines to sell ya.

You beat me to the punch..... so basically this guys is saying: that the thermostat gives resistance to the coolant flow and this is what prevents a car from overheating............
Sorry dude that is wrong. The thermostat prevents the coolant from reaching the radiator so it has time to heat up, thus allowing the engine to heat up to operating temp...... so if you remove the thermostat the system will run free flow, allowing all of the coolant to run through the radiator all the time. It does not need to stay in the engine for a certain amount of time to pick up heat..... it is running free flow so cool water is constantly running through the engine therefore the engine will not overheat (except for in this case where the fans will not turn on).
OP- when you removed the thermostat did you replace the coolant? If you didn't this is why your car is overheating and the fans are not turning on. The temp sensor for the fans is measuring AIR which is not a good conductor of heat. So as the engine is heating up the air is not getting hot enought around the sensor so the car thinks it is still cool......

Here's a good start. http://www.2carpros.com/dia/test_thermostat.htm
"Never run an engine without a thermostat because the thermostat works as a system flow regulator as well. What this means is the thermostat has a specific opening that regulates the flow through the cooling system. If the coolant is allowed to flow to quickly through the radiator the coolant will not have time to transfer the heat it has absorbed. This will cause the engine to overheat"
