So I'm reading Trials of Apollo and Apollo mentions that his father, Zeus, always prefers Artemis over him. In my head I thought 'why? Apollo sounds like the stereotypical golden son.' And then I realized. I made not only one pun but TWO puns.
"Golden" and "son" (son/sun)
So I started hysterically laughing. My dad, who sat next to me, gave me a look of concern and proceeded to ask me why. I told him and he just kind of rolled his eyes. Lolol
