Once! I gave money to PBS because of several shows I enjoyed watching, one being Dr Who starring Tom Baker.I had to move to get them to quit sending me “give me more money” forms! The only one worse than them was the “Christian College” in … Virginia? I sent them $35 for a big ol’ book, ‘splaining the Bible. I had to threaten them with Charleston Air Force Bases’ Legal Office to make them leave me alone!
