What's the fastest way to gain weight?

Hello,

I'm 5'2" and weigh 95 lbs.  My goal is to gain 15 lbs.  According to the weight calculator, I need to consume about 2263 calories a day in order to reach 110 lbs by March 25, 2009. 

What are some foods that contain huge amount of calorie besides junk food? 

Exactly what I need.

Apart from my specs:

I'm 5"9.5, male and around 140lbs. I want to put on like 15 pounds.

Suggestions please? (minus junk food)
