What I Learned From: Lethal Weapon 3

Danny Glover helps Damon Hines shave in Lethal Weapon 3.

It's a tender moment between a father and son, made more delicate by the surrounding context of the scene, when Murtaugh teaches his son Nick how to shave properly in Lethal Weapon 3. Watching his boy shave up, Murtaugh gently corrects him:

"Go with the grain."

In other words, shave down, not up. May seem a simple thing, but it a helpful tip that may have snuck by some folks.

You're never too old for some shit, like learning how to shave.
