Charlie Sheen’s replacement shares a primal moment with Jon Cryer and Angus T. Jones at the CBS upfront Wednesday

Getting your Trinity Audio player ready…

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.
