I Know Now from Snoopy!
"Hobbes did you ever think how many things we'd do differently if we already knew what we now know?"
"Sure, like how you can't bend a cracker."
"Sure Hobbes, I was thinking more like, if you steer a sled into a tree you crash instead of going through."
"Look out!"
"Or not getting a time warp going down a hill."
"Duck!"
"Or that you're a dummy who gets lost if I don't keep you with me"
"Eek!"
"Wouldn't it be great to go back and do things differently Hobbes?"
"Yes, oof, I wouldn't have gotten on the toboggan."
