lol, Charles!
There are very real benefits to having more correcting "exposure". Check out this thread here started by Shiraz (Ray):

I take around 20-30 flats but I'm lucky enough to be able to do so with an LCD screen so my exposure times are very short. I'll likely increase the number of flats I take in future as there are very real benefits to having a very clean signal. Flats correct for dust or vignetting that is reducing the signal that you should be getting.
Bias shots are the shortest exposure you can get anyway, so you'll want lots of these - at least 50 I think. Too few of these can result in a smeared looking background if the sky shifts relative to the camera over time.
The value of darks depend on whether you take long exposures and whether your camera produces a lot of thermal noise. It's essential to take them at the temperature as the temp you used to take your light images. I generally don't bother with them. If I move to 5 minutes subs I'll consider it - and then I'd consider 20 to a fairly minimal number.
Hope this helps,
