The ultimate fanbunnies.

Simon and River are huge fans of Neil deGrasse Tyson because he makes astrophysics come alive and more importantly, because he's nice to bunnies.
They're a bit jealous that we get to attend one of his speaking engagements but they can't come along because bunnies aren't allowed at the venue.

River is adamant that we let Dr. Tyson know of her disagreement with him on Pluto's planetary status.
