Panel 1:
(Penelope enters the server room, clearly pleased with herself.)
Penny: Well, I completed my First Aid training! I thought I'd never get that certificate!

Panel 2:
Johnny: I'm sure the instructor thought the same thing.

Panel 3:
(Penny walks to her desk.)
Penny: What's that s'posed to mean? She told me she'd never had a student with such a UNIQUE approach to first aid!

Panel 4:
(Penny takes her seat and begins to read a book, angrily ignoring Johnny.)
Johnny: I'd imagine that's because most her students know the difference between "First Aid" and "Last Man Standing."
