I came across some pictures on my Facebook feed of children screaming, crying and running away when they'd been seated on a festively decorated sofa for photos and a figure dressed as the Grinch apparently jumped out and scared them. Kids varied from around age 4 to about 12, I'd guess. Lots of people find this sort of thing funny, according to the responses it had received- do you? I just feel sorry for the kids. Do you prank your own kids?
