Dave: Amber, do you want some pineapple?

Amber: Sure *goes in kitchen*

Dave: Here *hands Amber massive hunk of drippy pineapple*

Amber: It's too BIG!

Dave: EAT THE GODDAMN PINEAPPLE!

Amber: ok

Dave: I should have said 'that's what she said'

Amber: what does 'that's what she said' have to do with pineapple?

Dave: When you said, 'it's too big!'

Amber: *chokes on pineapple*
