Word: Fight
Pairing: Phineas & Ferb
Giant Rock-'Em-Sock-'Ems were the subject of the daily activity. Phineas was operating the red one while Ferb was the master of the blue.
"Get ready to get socked, Ferb," Phineas said through gritted teeth.
"Au contraire, dear brother," Ferb replied cooly.
The two brothers fought valiantly against each other, beating giant plastic fists against robot torsos in a brave attempt at victory. Ferb struck the final blow, sending Phineas' robot sprawling.
Ferb rushed over to his luckily unhurt brother. "Phineas!"
Phineas made the robot stand and walk back over to the ring.
"Best two out of three?"
A/N: This was a request from BroadwayFanGirl91. I thought that nothing embodied good-natured sibling rivalry more than giant Rock-Em-Sock-Ems. Thanks for the inspiration!
