A Boston priest has been arrested on charges of stalking Conan O'Brien. (Hey, for once at least it isn't child molestation.) The twisted padre contacted the talk-show host's parents and has been bombarding him with threatening letters since 2006. When he was denied entry to a taping of the program, his next missive asked, "Is this the way you treat your most dangerous fans?"

A prominent Jesuit priest who traveled around the globe as a spiritual shepherd brought a teenage boy on at least one of his international trips and molested him repeatedly, federal authorities charged Friday.

Rev. Donald McGuire faced a judge in Dirksen Federal Courthouse on charges that he traveled to Switzerland and Austria in December 2000 to engage in sexual misconduct with a minor, who is now 21 and a college student.

But the affidavit against McGuire paints a portrait of a serial molester who targeted acolytes entrusted to his supervision. The accuser identified as Victim A told authorities McGuire sexually abused him from 1999 to 2003 in 12 states and six countries. His mother had sent him to live in Evanston with the priest, who had become a spiritual mentor to their troubled family.

According to the affidavit, Victim A and another boy were abused after admitting to McGuire during the sacrament of confession that they masturbated. McGuire insisted on inspecting the boys' genitals with a magnifying glass and baby oil to make sure they had not harmed themselves, the affidavit said. The abuse escalated to include discussion of sexual topics, pornography, massages of the body and genitals, showers and oral sex, officials say.

The third man corroborated the claims of Victim A and also alleged McGuire showed him pornography.

Victims A and B had filed civil suits against McGuire and the Jesuit order; Victim C had not come forward publicly until now.

Correspondence between families and Jesuit leaders, released by lawyers this week, appears to reveal a trail of allegations against McGuire dating to 1969. But Illinois' statute of limitations prevented prosecution on decades-old claims of abuse.

McGuire, 77, was convicted last year in Wisconsin of molesting two students from Loyola Academy in Wilmette during trips near Lake Geneva in the 1960s; that state's statute of limitations does not apply to out-of-state residents.

Is Conan still alive? I thought he commited suicide when Terrence and Phillip were arrested on his show.

Lots of celebs have stalkers. Hell, Bob Uecker has a stalker.
