Tristan McLaurin is a singularity often found around the Orian spiral arm of the Milky Way Galaxy, about 28,000 light years from the center of the Galaxy, and 20 light years above the galaxy's equatorial plane. Affects of the singularity can include math and science jokes, as well as puns no one seems to understand. Some have claimed there are many claims and references to a correlation between the occurance of Doctor Who broadcasts and Tristan sightings, but these are as of yet unconfirmed.

During Tristan Singularities Guitar music can occasionally be heard, and Banana Smoothies will mysteriously disappear.
