I hesitate to be snarky about this, because all of the evidence on lead poisoning and the long-term effects it can have on children is nothing to be funny about. But I can’t help but remark on Oliver’s use of Sesame Street in this clip, which is a neighboring HBO property as of this year.
Of course, it’s not the first time Oliver has joined with the Muppets, or Sesame Street. (His previous appearances with them were all prior to the HBO deal as well.) So perhaps we can chalk it up to him loving the zany furballs as much as any Muppet head would.
