I got caught staring at a construction worker once, and I'm male....

Standing at a pay phone on hold, hot summer day, dude wearing only the orange vest with just killer biceps. My thoughts were along the lines of "Jeeze, I wonder how he got those arms, are they from free weights or machines? I wonder if I can ever in this lifetime get arms like that?"

Dude walked up to me and gave me the old "Whaddya lookin' at f*g?" in his best construction worker voice.

Well, what could I say? I told him the truth. He was cool about it and told me that the arms came from free weights. ;-)
