Swedish also has a funny name for the @-sign, named after the trunk of an elephant. In fact, quite a few languages do. Here's a short sample from the Wikipedia article:
In Swedish and Danish the sign is known as the "snabel a" (literally trunk a), owning to the resemblance between the sign and the trunk of an elephant. In Norwegian the term most commonly used is "krøllalfa" (literally: curled alpha). In Greek the sign is known as "papaki" meaning small duck. In Slovenian, the most common word for it is "afna", colloquially meaning "monkey", much like in Polish. In Hungarian, it is called "kukac" meaning "caterpillar".
