Happy Friday!

Via Cassandra: I did not know that HexBugs were also cat toys. The more you know!

Via John Green: DNA solves a Presidential genealogical mystery! Warren Harding’s “love child” is proven to be his, genetically.

Serious question: Do you remember these Bears as Berenstein or Berenstain? There’s a whole theory built up around what you remember.

And finally: It is a (possibly little-known?) fact that I love Motown, so I leave you for the weekend with this completely awesome performance by the third, fourth, and fifth-graders of Baldwin Hills Elementary in Los Angeles. (If you like this, there’s a whole bunch more videos, including a jaw-dropping rendition of Janet Jackson’s “Rhythm Nation.”) Have a spiffy weekend, everyone. See you next week.
