Yup. They created this fake feud between them as a running joke. People forget the shenanigans that Donald Trump did with wrestlers in boxing events, and the gag feud between Arnold and Sylvester Stallone. It's all games with these guys.
Yep, they’re trying to gin up an artificial controversy. It’s to Trump’s advantage to give the media a shiny toy to distract them, and it’s to Arnold’s advantage to hype ratings for “Celebrity Apprentice”. The media falls for it, while Donald and Arnold are secretly laughing their asses off.
