"Waarom Waarom Waarom" (translated as "Why Why Why") is a song from the 1983 Sesamstraat album Maak Er Wat Van! featuring Bert and Ernie.

After Ernie experiments to show how the earth revolves around the sun, he and Bert sing some queries about why or how things happen. Why does it snow in winter and why does the sunshine in summer? Why does milk come from the cow? They even ask why poop comes from the rear end.
