ULPT: Volunteer to spend time with senior citizens and go through their old pictures with them. Snap photos of the ones where they're hot and claim they're your grandparents on Reddit for sweet karma.

For even more comment karma, act like you're embarrassed by comments about how hot they were. Say stuff like, "Oh no. What have I done?" or "RIP my grandma's inbox." And then when someone makes another joke about your grandma's inbox, then you act like you didn't know you were setting them up and say something like, "Oh no, I'm only making it worse" for even more upvotes.
