"The body is a temple - and you have defiled yours!" Bulk Biceps switched to a side chest pose, his massive muscles flexing like cabled steel.
Across the green, Tirek twisted around into a rear lat spread. Oil and sweat gleamed in the sun. "Weak excuses for a weak form! A true bodybuilder would never let such trivial concerns stand in their way!"
Bulk shifted, gathering all his muscular mass forward into a looming front double biceps. "That body isn't your own! It's stolen and artificially enhanced - there's nothing in it to be proud of!" His namesake biceps bulged. "YEAH!"
Twilight gagged - hard. "Dear Celestia, I can smell the testosterone. How long have they been at it?"
"Three and a half hours." Applejack paused to loudly sip her drink. "Heavy casualties. Six mares an' two stallions fainted. One nosebleed. An' Big Mac snapped his back tryin' to copy them."
Now, this one was so funny! Typical guys thing, ya know...
