This. In fact, I still do things for relatives that I don't want to do, just because my grandmother would want me to. She's been gone for 8 years.
They all died for i could notice, even though i could not punch any of them, not for anything on earth.
I don't think it is the seriouness of it as much as it is respect for the Grandmothers. Even in fun I wouldn't suggest that I would punch my Grandmother for anything in the world. I know the thread was intended for fun.
I just can't joke about my grandma, sorry. I will, however, kill a hobo for a pair of jeans that fit.
I've never had a grandmother (or a grandfather for that matter!) in my life so.... anyways, I couldn't punch my way out of a paper bag.
