I know a lifted Jeep with big mud tires isn't going to run or drive as smooth as one straight out of the factory, but how drastically will a lift and big tires effect the gas mileage of the Jeep?

What gearing/tranny/size/weight are all going to determine the loss in PG's

Larger tires and wheels = more mass and inertia. The engine has to work that much harder to overcome the inertia when stopped at a stoplight and accelerate the vehicle to speed. Larger tires can also mean a larger contact point with the ground and that means more friction.
A harder working engine consumes more fuel for an equivalent outcome and that equals lower miles per gallon realized.

If you get the tire size/gearing right, the effects can be minimal.

Is this a serious question?

I was already fairly geared (Rubi). After a 33" x !2.5" x 15" tire and wheel swap I didn't really notice any diff in my MPG.
