"Two and a Half Men"
COMEDY. Charlie Harper is back — sort of. It's unlikely Charlie Sheen will ever set foot on the "Men" set again — remember the whole tiger blood thing? — but that doesn't mean the writers can't have some fun with his character, who appears as a ghost after Alan has a minor heart attack tonight. In a stupendous act of stunt casting, Kathy Bates pulls on the requisite bowling shirt for the role of the deceased king of debauchery.
9 p.m., CBS
REALITY. It's "Mad Men" minus the '60s-era office sexism, smoking and drinking when two real-life ad agencies compete for the business of big clients.
Series premiere, 9 p.m., AMC
"Money From Strangers"
REALITY. Need a sign that the economy isn't getting better any time soon? This new hidden-camera show finds people willing to do ridiculous and/or humiliating things in public for cash.
Series premiere, 10:30 p.m., MTV
