Optimus Prime is telling one of his stories to Strongarm one of his stories.

Optimus Prime: "And the flanking action allowed us to route the decepticon forces."

Strongarm: "Amazing! Tell us another!"

Sideswipe: "Ugh, give it a rest, will you Strongarm. You bugging pops for war stories is getting older than... well, pops!!"

The words repeat in Optimus Prime's head.

Optimus mind: "What... did he... just call me?"
