There's a guy at my job who used to be a crackhead. Sadly, it works to his advantage because he has massive metabolism. While he eats like a pregnant pig, he gains NO WEIGHT. But to his disadvantage, that also applies to working out. While he's pretty well cut, he's pretty much skinny.
The point, however, is that ever since it's become known that I've always been a long time fitness guru at work, he's suddenly claiming to workout alot too. But I tend to catch him in his lies since he have no clue of the names of exercises. One day, we're working on the fuel lane together and as I'm about to take off with a bus and bring back another, he approaches the front door and flexes. He tells me, "Check this out. 13 inch arms." He felt so happy about them until I told him, "Dude, that's below average. How do you claim to workout so much but yet, you have the arms the size of a 13 year old boy?" He felt like shit after that and never talked about it again.
