Sounds like a great time to ask how satellite TV works if the world is a frisbee. That turkey is gonna get cold while he tries to explain the broadcast angles. Some battles just aren't worth the lumpy mashed potatoes.
My cousin Nate brought up chemtrails at a Thanksgiving dinner a few years back. My uncle, a retired airline mechanic, just stared at his plate for a solid minute before asking Nate to explain the plumbing on a 747. It turned into a whole shouting match and the turkey got cold. Sometimes calling it out just makes everything way more awkward.
That uncle stare sounds like it carried more weight than the whole argument. Is a cold turkey really worse than letting that stuff slide without a word though?
