charlie sheen 2 getty Charlie Sheen Roast promos   Welcome to the 'Crazy Train'If ever there was a exchange that explained Charlie Sheen, it’s this one Comedy Central commercial released Tuesday (Aug. 30) promoting the upcoming Sheen roast.

Sheen, acting as a train conductor, takes a moment to help out a needy female passenger.

“Charlie, does this train stop in Normalville?” questions the busty traveler who sits among tigers, warlocks and men in diapers.

“Honey,” he responds, “we left there a long time ago.”

The network recently announced it signed comedians Jeffrey Ross and Anthony Jeselnik as well as Mike Tyson, TMZ founder Harvey Levin and “Jackass” Steve-O to rip the former “Two and a Half Men” star. It will be hosted by “Family Guy” creator Seth MacFarlane.

“The Comedy Central Roast of Charlie Sheen” airs Sept. 19 at 10 p.m. ET.

Here are the spots.
