Has Ashton Kutcher already fallen out of favor with his new "Two and a Half Men" colleagues, Jon Cryer and Angus T. Jones?
Naw, not really; the three new amigos are merely pranking the world, via Mr. Demi Moore's ever-active Twitter account.
Following Wednesday's CBS upfront presentation to advertisers in New York, Kutcher — who last week inked a deal to step in for a departed Charlie Sheen on Men — headed over to Carnegie Hall for a little jovial fun.
"First cast argument 2.5 men (@ Carnegie Hall (Isaac Stern Auditorium / Ronald O. Perelman Stage) w/ 39 others)," Kutcher wrote.
Apparently, "practice, practice, practice" isn't the only route to Carnegie Hall — a little bit of shouting will get you there too.
