The old "what are you training for?" one. If I had a $ for every time I've been asked that, I wouldn't be bothering looking for another job right now. I remember once, I was eating a greasy hamburger (not my normal choice for meals, but hey, there aint a lot at Jackadgery) 120km into a ride and I got asked this question. I felt like saying "would I be eating this if that were the case?"
