Baker's dozen is a period 12 oscillator consisting of a loaf hassled by two blocks and two caterers. The original form (using period 4 and period 6 oscillators to do the hassling) was found by Robert Wainwright in August 1989.

By rephasing and moving the caterers, it is possible to get a 37-cell variant. Using mazings would also work.

It can be stabilised and welded in many ways. A caterer can be used in 2 ways, one way is also suitable for the jam. A mazing would work, and two can be stabilised next to each other. 2 opposite ones can be stabilised with 2 bookends (shown as bookend on snake) in the lifeviewer.
