Charlie Sheen: Stay Off Crack, Drink Milk (Video)

The "Two and a Half Men" star, who is undergoing rehab, gives an antidrug lecture to the UCLA baseball team.

Do as he says, not as he does.

Charlie Sheen, who has been undergoing rehab at his home after being rushed to the hospital last month, gave an impromptu anti-drug speech to the UCLA baseball team.

"Stay off the crack," Sheen joked in a video featured on "Enjoy chocolate milk… enjoy every moment. That's all I got. Have fun!"

The team laughed and clapped after he was done.

Production on Two and a Half Men has been halted, potentially costing upwards of $250 million in domestic syndication deals, while Sheen receives treatment.

The actor has offered to pay a portion of the salary of the show's staffers.

His rep has said he hopes to be back to work by the end of this month.
