Boffo STUPIDITY

At some point in the post-Boffo storyline, Dei fakes his own death for tax purposes, among other things. This was during one of his periods of radio silence; Opal and Tyler were sent a copy of his death certificate in the mail after not hearing from him for years. Tyler was distinctly unamused by this turn of events; he was even less amused by Dei's choice of tombstone:

Tyler stared blankly at his brother, while Opal hid her face in the voluminous sleeves of her sweater, shoulders shaking with tears, laughter, or both.

Dei met his younger brother's glare with a sheepish grin. "What?"

"If Dad weren't already dead, he'd kill you."

"Oh, come on. You know he'd get a kick out of it. It's funny. You know, a joke?"

"It's your fucking tombstone!"

"Exactly. It's my tombstone, I can put whatever I want on it. Lighten up, Tyler. It's not like I'm going to be using it any time soon."

"That's what you think!"

Opal managed to avoid getting caught in the ensuing scuffle, but the tombstone was not so lucky. Tyler proclaimed himself the victor over its shattered pieces, still glaring at his brother despite the way his left eye was swelling shut. Dei emerged from the fight completely unscathed; he put his hands in his pockets and met Tyler's glare with a resigned sigh.

They were both idiots, Opal decided- but they did keep things entertaining.
