A video
There was an episode of Diff’rent Strokes where Willis had a hard time making friends at school. Mr. Drummond gave him some advice. Willis took his advice but it did not work. In real life, I dared myself to try this out, but my future self always said no. Mr. Drummond was played by Conrad Bain who had a real life twin brother. In this video, he uses the ice-breaking tips for making new friends with his twin brother in order to show that it really works.
(Conrad plays his brother. (His brother’s name is Bonar.))
