"Yes football fans, that's ANOTHER TOUCHDOWN by Calvin Boavida for the home team! This game just got CAL-O-RIFIC!"
"Wow, he may not be light on his hooves, but once that boy gets his butt moving, it seems there's NOTHING short of a candy-store that can stop him!"
"And don't the opposition know it! Anyone get the number of that steamroller, boys?"
"He's a one-bull stampede!"
"He went through them like he was in the cafeteria chow-line for lunch!"
"THAT'll teach 'em not to mess with the Big Bull on Campus. There's been talk of Coach putting the Colossal Cow on a diet, but it seems the crowd can't get enough of him!"
"He's sure working up a sweat out there. Let's just hope the Team have plenty of snacks waiting for him in the locker room! Not that his uniform will thank them for it!"
"Uhh... are we broadcasting in the stadium too...?"

People queried whether how Cal was still capable of playing football at his somewhat beefy size. The answer is- by being pretty much unstopp-a-bull. It's certainly made him popular fodder for the college commentators. Not that he really gets it, of course.
