What life lessons have you learnt from the boys that you will never forget?

Now that my credit card (and patreon subscription) has expired, I'm reflecting on the wise words of wisdom I've received over the last few years.

Personally, I will never forget prone (like a drone) vs supine (soup's on).

And if a so-called "gentleman" ever tries to present his dirty nails to me in the prone position I'll know how to handle the situation.
