This example of very worthwhile trolling is from the winter, but I hadn’t seen it. Also, the video only had 3,000 views as of this morning, so chances are you haven’t either. Furthermore, some cliche about Christmas in July or something. Anyway, the premise is that a 49ers fan married into a family of Raiders fans and is now handing them Christmas presents. No better way to ingratiate yourself than to play on the Bay Area rivalry with a football-related gift. With a deft touch, you can even insult their allegiance yet not come off as a dickhead. To that end, this guy does a commendable job. Well done, sir.
