No, not me
Ways to tease/annoy oldies:
1. Persuade a friend to walk around the house dressed as the Grim Reaper and maintain that you can't see them. That usually spooks 'em.
2. Convince them that they're confused by introducing yourself to them at 10 minute intervals, each time maintaining that you're a different grandchild.
Any other cool ways of abusing the aged?
