Just when you thought there was a sense of calm in the celebrity Twitter feud universe, Charlie Sheen has decided to pick on Denise Richards.

As Popeater reports and Sheen’s Twitter feed confirms, the former “Two and a Half Men” star turned professional warlock (or something) has called out his ex-wife for allegedly taking away their dogs.

However, Popeater’s Rob Shuter reports that Sheen gave the dogs back to Richards and that, technically, the two pugs, one of whom recently died, originally belonged to the “Wild Things” star.

If an anti-Denise Richards rant is Sheen’s plan for a nightly grand finale during the “Torpedo of Truth” tour, expect even fewer people to want the remaining tickets.

Meanwhile, Richards wins today’s #Irony Prize: she’s been tweeting today from a puppy shelter where she’s shooting a segment for A&E.
