One of my favorite achievements at Google was my ultimately successful year-long struggle to convince the YouTube TV team to fix the comma splice in their "We'll be right back, enjoy the zen." [sic] interstitials.
I loved the relaxing scenes, but every time one of them showed on our TV, the neighbors could probably hear a Charlie Brown-esque AAAUUUUGGHH! from our living room.
This went on for months.
