Smithers, Homer and others in “Simpson Tide”

Uh, sir, we found the problem. Some idiot threw this in the reactor core.

Homer

[sees charred doughnut] Success!

You did this? How could you be so irresponsible?

Homer

Uh...it's my first day.

Since I've never seen you before, maybe it is your first day. Very well, carry on! [walks off]

Sir, that's Homer Simpson. He's been working here for ten years.

Ohh, really? Why did you think you could lie to me?

Homer

It's my first day.

Well, why didn't you say-- Yawoo! You're fired!
