20D off counter onto toddler's foot

My 19 month old son pulled my 20D (with attached 17-85 lens and 580EX speedlite) off the kitchen counter this evening and it landed on his foot and granite floor. Thankfully all the toes are in tact and not broken, but the camera didn't work after the fall. I switched it on/off and that didn't get it to work. I then pulled the battery out and put it back in and the camera started back up. It seems like everything works now, but is there anything I should watch for or specifically do to make sure the camera is working properly? Should I take the camera in for a service "check-up"?

camera should be ok id think, but maybe take a few test shots with the lens to see its still good.

heh...
I had an old Nikon 8008 fall six feet onto a wooden boat deck and work fine, and the N90s fall three feet onto the same wooden boat deck twice and be perfectly ok. The hood on one of the 300 f4's was bent a bit but it didn't affect the images.

Nikon: like a rock!

(I also had the same 8008 shutter block completely shred itself to bits out of the blue once. that sucked.)
