Hehe, reminds me of my experience @ YYC in April.

Agent: NEXT
Me: Good morning Sir. How are you?
Agent: CITIZENSHIP?
Me: Netherlands
Agent: WHERE ARE YOU GOING TODAY?
Me: San Francisco
Agent: HOW LONG ARE YOU PLANNING TO BE IN THE US?
Me: Two days
Agent: stamps passport and shouts "NEXT"

There were no lines around 1030am and I was through in 5 minutes.
