[... This guy bit into a whole lemon, didn't he, by the sounds of it.]

The only reason most people ever eat the peel -which sounds like you did- is when the lemon is sliced and candied. [Or zesting said peel for a dish.] The sourness of a lemon can add to a lot of dishes, and there are people that do enjoy it on it's own. Some lemons are sweeter than others, too. People like lemonade, a drink made from lemon juice, water, and sugar.

[Of course this may as well be happening today. Why not.

Friendly type, and something else—]

I don't hear that often. [Or at all.]
