Martin van Waardenberg

From Muppet Wiki

Martin van Waardenberg plays Buurman Baasje on Sesamstraat, the Dutch co-production of Sesame Street.

Buurman Baasje (Next Door Neighbor Bossy) is the grumpy neighbor who lives around the corner, behind a big fence. He hates it when Tommie, Ieniemienie and Pino disturb him, but with the help of the other actors, he is usually a victim of his own grumpiness.

Buurman Baasje's real name is Mr. Drommel; when the new neighbor called Tommie "baasje" in his debut episode, Tommie invented his nickname.

Buurman Baasje was added to the cast when Aart Staartjes, who originally played the grumpy character on the show, announced that he would be retiring from all children's TV except Sesamstraat. Since the new neighbor's arrival, Aart has become a little tamer.

Martin van Waardenberg is a comedy actor and a part of the duo Waardenberg & De Jong.
