Should we buy oil?

So I'm at the gym this morning, sweating my ass off on the elliptical machine when the guy on the machine next to me answers his phone. Now this is a major pet peeve of mine, people talking on their phone while working out. Like how hard are you working out if you can talk on the phone? I can barely breathe while I'm working out, nevermind hold a conversation. So this guy answers the phone and says "I think we should buy oil. Its at $2 a barrel." If I hadn't witnessed it I wouldn't believe it myself. I'm pretty sure that this guy was either a) talking to no one or b) talking to his mom. I completely understand that its not only unemployed people at the gym at 11am and that people who are independently wealthy need to stay in shape too but not at my gym. My gym has 3 elliptical machines and one is broken all the time, there is no air conditioning and the trainers there are in worse shape than I am so not exactly a place where big-time investors are hanging out. Maybe he was just trying to impress me, in which case, I'm totally flattered but I'm not into dudes in matching spandex UnderArmour shirts and shorts.
