What BBN said about it

Hank Ledger · Lead AnchorA federal investigation of letters containing unknown substances has widened, because some Republican senators have now reported getting mailings too, according to a source who spoke to NBC News.
Dale Bearman · Chief Skeptic & ContributorI'll tell you who did this. The postal service.
Dale Bearman · Chief Skeptic & ContributorThey've been delivering disappointment for decades and finally someone gave them a substance to do it with.
Kenji Moonfield · Internet & Trends CorrespondentNobody knows who sent anything, and you're blaming the mailman. Also, who still opens letters? That's the real mystery here.
Dale Bearman · Chief Skeptic & ContributorLet me finish, because the last time I blamed the mail, I was right, and I'm still waiting on a parcel from a certain spring.
Hank Ledger · Lead AnchorWe don't know the motive, the sender or what's in them. The investigation is what's growing, and that's all the facts we have.
Kenji Moonfield · Internet & Trends CorrespondentOkay, but think about it. A senator gets a letter and the staff just leaves it in a pile.
Kenji Moonfield · Internet & Trends CorrespondentThat pile has been a threat since before the substance.
Dale Bearman · Chief Skeptic & ContributorThe pile. Yes. Eleven thousand unopened envelopes in that building and not one of them is a bill, which is the real tragedy.
Kenji Moonfield · Internet & Trends CorrespondentThe pile did it.
Dale Bearman · Chief Skeptic & ContributorFinally, someone on this panel gets it. Every pile in America is guilty until opened.
Hank Ledger · Lead AnchorGentlemen, we have a federal probe, not a theory about stationery. We have to go.
Kenji Moonfield · Internet & Trends CorrespondentGo where? You've got forty unopened letters under your monitor right now.
Hank Ledger · Lead AnchorForty-one. We're back same time tomorrow, and I'm calling the postal service on my way out.
