I recall a video (I think it was Veritasium) which featured interviews of people specifically being asked to give a "random" number (really, the first one they think of as "random") between 1 and 50. The most common number given was 37. The video made an interesting case for why.

(It was Veritasium but it was actually a number from 1 to 100, the most common number was 7 and the most common 2-digit number was 37: https://www.youtube.com/watch?v=d6iQrh2TK98.)
