Not a pun, but word-related
A friend of mine at uni told the story of how, during an evening's conversation in a pub, the subject turned to words such as crash, bang, smash, splash, and what those words are collectively known as.

One guy in the group said, "oh yes, that's what's known as an onomatapeia", then turned to my friend and said, in a very smug and condescending tone, "that means a word that sounds like the action it's describing - you can add it to your English vocabulary".

To which my friend - who was Greek (and had a thirst for Guinness as well as knowledge) counted slowly to "deka" - before saying, "no, we Greeks find a lot of those long English words very difficult to understand..."

The patronising git is probably still trying to work out why the entire table (bar him) burst out laughing...
