Dad: The trick to balance... «Calvin and Hobbes: It's A Magical World»

Dad: The trick to balance is to have a little forward momentum.
Calvin: Aaa! No momentum! No momentum!
Dad: Just pedal slowly. I'm holding the bike, so you won't fall.
Dad: You'll let go and the bike will launch me into the lonosphere.
Dad: Trust me, ok?
Calvin: Trust you? I hardly know you!
Dad: I' your father!
Calvin: What, for six years?! When I'm 40, we'll see how things are going!
