What's Your Favorite Design Pattern

Once in a job interview, someone asked me "What’s your favorite design pattern?". I was first surprised at the question. Usually a design pattern is about solving a problem not about a personal preference. I wondered if it was a trick question of some sorts. I was hesitating with my answer and asked more about the meaning of the question. I just had to really give the pattern I liked the most! I really should not have but I ended up pleasing my interviewer and said "the decorator pattern". At least its name is somehow related to arts.

Then he said his favorite one was "the template pattern". He was really into it because he could use it anywhere. For him it was like the best thing since sliced bread.

Sheesh! just an abstract class. What kind of pattern is that!?! Design Patterns discussions can be really dull.
