Yeah, I've seen a few weird ones listed over the years.....Bill Clinton, Stephen Hawking, the Queen (!).
I don't normally read much into it though tbh...unless it was Rolf Harris or Jimmy Savile, etc, etc, then I'd be steering well clear!
Same goes with favourite drinks to a degree...lots of them seem to really like champagne or funny (expensively) named cocktails, probably because they think it makes them sound classy. Rarely do they have "a cup of tea" listed!
