Translating an English language TV program into Spanish can be difficult. There are a lot of idiomatic expressions and concepts that cannot simply be translated word-for-word for them to make any sense. I submit to you a simple, but effective example.
Sponge Bob Squarepants (or simply Bob Esponja as he is known in Spain) has a neighbor named Squidward. This is a play on a Squid + the name Edward. To translate this name into Spanish, the concept of a squid is first translated (Calamar) and then adapted using the same, albeit altered, formula. So Squid + Edward becomes Calamar + Eduardo, and hence Bob Esponja's neighbor is Calamardo.
