Double minimal pairs

I found an interesting coincidence as I was working on the Tirelat
vocabulary: a pair of words that's a minimal pair in both English and
Tirelat.

żuki ['dzuki] "drain" (n.)
žuki ['Zuki]  "train" (i.e. railroad train)

How likely is this in unrelated languages? Is it possible that when I
went to come up with a word for "drain" that the older word for "train"
came to mind? Or is it just one of those coincidences that's likely to
come up with a large enough vocabulary?

Does anyone have examples of minimal pairs like this from their own
languages (which translate to minimal pairs in an unrelated language)?
Now I'll have to see if I've got any other examples of this.
