What is this lump?

Friday night I went to a program with some old friends. While catching up with one guy he started telling me about his job. He owns a fitness center. I commented that he probably sees quite a few crazy people. He started laughing and said, "Yeah."

He told me about this old man who is about 80 years old that started lifting weights about 4 weeks ago. One day this old man came over to him and said, "I'm a little worried. After I started lifting, I got this lump in my right arm. My wife thinks I need to go to the doctor, but will you just feel it and tell me what you think." My friend said, "Sure. Let me feel it." So he feels this guys right arm and then asked if he could feel the guys other arm. He felt the two arms a couple of times and then started to chuckle a little bit.

He said to the guy, "I don't think you need to see the doctor. This lump in your arm is a bicep." The old guy hand been doing curls with both arms, but was only lifting with his right arm. Just goes to show that you are never too old to pump iron.
