Brainley and Dobbsey are in the lab. Brainley is wearing an expedition hat.

Brainley: I hereby challenge you to a race around the world! The first course will be hot air balloons, followed by a yacht course --

Dobbsey (interrupting): Er, Professor, we did that last week.

Brainley: We did? Who won?

Dobbsey: No one. Your hot air balloon caught on the university chapel spire.

Brainley: It did?

Dobbsey: Yeah, it was a huge wreck. Don't you remember?

Brainley: Er...no. No I do not.

Dobbsey: You know, you hit your temporal lobe pretty hard. Maybe you should go lie down or something.
