Japanese spider crab Puns

My parents are both immigrants from Taiwan and came in the mid 80's. We've always owned restaurants (currently have a Japanese steak house this is important for later) so their English isn't all that bad and has improved over time. I've never gotten a single dad joke from him. Ever.

Que yesterday we are driving home from a family dinner to celebrate his birthday. We all get into the vehicle and my mom says in Chinese "You've got something hanging onto your shirt, it looks stringy. Is that a spider web?"

I respond, "What? That's his pet, he can't raise a pet spider?"

Dad says, "Yeah I raise them really big and fat so we can make spider rolls at the restaurant." (Spider roll is typically softshell crab in a roll with other stuffs for the non-sushi fans out there)

I groaned, chuckled, then reveled in all that was my first dad joke. It was awesome. Thanks for reading guys! Sorry it's so long.
