For some it's just a beloved ritual and shared experience :-)
I've certainly seen it at least as many times sober as I have seen it drunk. First as a kid of course, but also now that I'm older (even though we have no kids and no other requirement not to drink). I have to admit it's funnier while enjoying a nice drink, though ;-)
