Ulf is the funniest person to ever walk the face of the earth. He is intelligent, hard-working, and can always put a smile on your face. His laugh can travel through universes and never sees to exist. He is the best dad, and would care for you like no other person ever will. He is absolutely amazeballs and the best person to watch a movie with. "He would walk through fire just to make you smile!"

Kajsa: "Ulf you wanna watch a movie"
Ulf: "HElls to the yes! HAHHAHHA you know which one ;)"
