We don't talk about being buff all the time, just most of the time.

Today my brother Connor told me his female gym teacher had biceps as big as his head. Connor's head is very big.

After Connor said this I immediately remembered an odd, and very buff, acquaintance of mine. [Note: This acquaintance's buffness is incidental to her oddness. I have nothing against people, of either gender, who are buff. Kumbaya.]

Anyhow, this acquaintance once said (among many other things) that she would only date men she couldn't bench press.

Simultaneously I remembered this acquaintance and was struck with a strong desire to be both witty and humorous. Consequently, I told Connor: "I only date men I can bench press," when I really meant to say, "I only date men I can't bench press" and thus allude to our shared buff acquaintance.

Connor laughed heartily. Not because he remembered our shared acquaintance, but because I can't bench press anything, much less a man.

Moral: I guarantee my biceps are smaller than your head.
