Another joke from the Caderno that I didn’t get at the time but have since had explained to me
Estão um pargo e uma lula a conduzir e o pargo ultrapassa a lula de maneira brusca. Vira-se a lula:
-Tás pargo, pá?
-Calula
A Lula is a squid (I knew that) and a pargo (well, o pargo, but you know what I mean) is a red snapper (I didn’t know that but guessed it some kind of marine creature). And the unpunned version of the dialogue would be
-‘Tás parvo, pá?
-Caluda!
or
“Are you stupid, mate?”
“Shut it!”
Thanks to Fernanda for deciphering this fishy confusion for me
