Quote from Tim in A Battle of Wheels
Tim: Al, you didn't... you didn't get the stop in there. Al: I believe that was your job, Tim. Tim: Al, I believe you're my assistant. You're supposed to check up my work, right? That's what a good assistant does, right, Al? Al: A good assistant does a lot more than that, Tim. Tim: You're right, Al. And that's why Al and I plan these minor slip-ups. To demonstrate the importance of how a good assistant can prevent accidents like this. Isn't that right, Al? Al: I don't think so, Tim. Tim: I think what Al means is, if you're not careful and watch your step. You can screw up, just like Al did. Tool Time tip: don't be like Al. See you next time, everybody.
