Earlier quoted context omitted.
Not only Vietnamese but a lot of languages all over the world, if not most or all. Puns and wordplay exist in any language, and people who say "why English/German/Swahili/whatever is so great for Y" merely have no deeper understanding of linguistics aside folk etymologies and lists of "untranslated words" (which are a joke to people actually into linguistics) and things like that.

Examples please. I love puns.
There was a Korean guy working in a Japanese company.
One day, his coworker went out to the roof for a quick cigarette break. Another person came in and asked where he was, so the Korean guy would reply (in Japanese), "Oh, Mr. Tanaka is taking a break, on top of the roof."
The person blushes, and leaves wordlessly. The Korean guy is confused, and then realizes he used the Korean word for the roof: "oksang".
(Japanese okusan = wife)
