A game while driving

What to do when you are driving (except watching what is going on on the road)? For quite some years now I look at the numberplates of the cars and try to find a word that fits the letters on it. There are only a few rules: the order of the letters must remain the same and you can add only vowels to create the word. the photo shows an example. The letters are PRL and that can make the month April (both in Dutch and English), but also Parel (that is pearl in English and that fits as well). So I look for Dutch, English, German and French words.
you like it? give it a rty, but beware it is addictive.
