Tjeerd 

The biggest instigator of smurfs country. He lives there with Smurfette, the cleverest of all smurfs country. Smurfs find Tjeerden unwise attractive because he is smart and also funny. Also Tjeerden are often naughty and have a fetish on refrigerator doors. Ideally, they polished refrigerator doors all day long. If you are Tjeerd, you should be happy to be called Tjeerdmans instead of Tjeerdo! Past-simple of Tjeerd is verdisconTjeerd.

Tjeerd is the opposite of Geert
