On my geekiest Christmas present

 I had suggested that I would like this to my siblings. Alice and Stephen bickered over who would get it for me. Alice won. For those of you who aren't up to speed, it is a Star Trek, the original series, bike jersey in the engineering/security department colour. The one downside of it, is that in the original series, people in red shirts were very often killed, to the point that in science fiction the term "red shirt" is often used as shorthand for "expendable crew member".

Merry Christmas!
