Doctor Who has a lot of silly little shorts like this for various programs, but this is one of the shortest I've seen and least substantial.  The Doctor makes some unfunny jokes and the writing really isn't there.  It's only a minute long anyways.  It did leave me nostalgic for Jenna Coleman, she's cute in this and it was a nice reminder of how talented a performer she was on Doctor Who.  Coleman was really good at giving this effortless feeling to her acting I appreciated here, and it does leave me thinking I was too hard on her as a companion when she was active.
