Well you're brave for calling this the Ultimate Homer Simpson Soundboard, I salute you for that. But what this soundboard lacks is the potential to produce a quality prank call.
If you're going to make a soundboard, you don't just record various quotes and put them in one place, you really have to take your time and find proper replies, funny things you can say to the person in the phone etc... Because if soundboards are not used for prank calls, whats good about them? Plus you could have included alot more sounds. The Simpsons has been running for almost 17 years. Better luck next time.
