Ok who has not wanted to do this after they take the 9 inch needle and smile while saying this won't hurt

Charlie Sheen isn't having the best week.

The 49-year-old actor is reportedly under investigation for pulling a knife on his dentist while in the chair last Thursday, according to TMZ.

Sheen was allegedly under the influence of "rock cocaine" and when the technician tried to give him nitrous oxide ahead of an abscess procedure, he apparently lost it.

Sheen's security had to enter the scene along with his dentist and the oral surgeon.

Sheen's technician is claiming the former "Two and Half Men" star pulled out the knife to go after the dentist, who was not harmed.

The Los Angeles Police is now looking into the incident as "possible battery against the technician" and "assault with a deadly weapon" for the apparent attack on his doctor, the gossip site noted.

Sheen has not yet been prosecuted.

News of this episode comes just one day after it was revealed that production was halted on Sheen's FX show "Anger Management" due to a face injury he got after mistakenly jumping into the wrong end of his pool, Sheen's rep told Radar Online on Tuesday.

"He was taken to the doctor and got stitches. He was out of work for about a week, but was back on Monday morning," his spokesperson added to the site.
