At least yours has a fairly happy ending. My brother got my mother a new tv one xmas, then proceeded to try to hook it up with the vcr (okay it was a while ago), only hes not great with the techie stuff, and he had the sound up full blast, and it kept switching between static and probably a football game, and after about ten rounds of this, i said, "Really?!" and went to my mothers room and hid my head under the pillows. I was later chastised for not politely asking for the sound to be lowered.
So my only advice is, bring earplugs.
