An analogy for obvious. This was originally coined by a pharmacy professor at the UT Health Science Center at San Antonio. The professor was referring to Phineas Gage, a 19th century railroad worker, who suffered a freak accident when an explosion catapulted a large piece of iron through his skull and into his frontal lobes. An injury that was anything but subtle.
Professor: "what's an antibiotic used for?"
Student Bob: "Uh, there is an inhibitory, Uh, upregulation and, Uh half life ..."
Professor: "An antibiotic kills bacteria. Bob, the answer was like a nail in the head and somehow you completely missed it"

Expressing oneself too directly, too plainly, insensitively.
I once considered buying a birthday card for my dad that made fun of his age. My dad was in his late 60's. It portrayed a man in a car looking in a rear-view mirror with a panicked expression, and seeing the Grim Reaper. The message printed on the mirror was, "Objects shown in mirror may be closer than they appear." I thought it was hilarious, but I thought it was "hitting the nail too squarely on the head." It's implication was too direct.
