The demo runs beautifully on exactly one machine. For developers who have watched a successful local test become a much less successful handoff, with Rex included.
Clean front. Loud back. A small REGEX wordmark sits on the chest, with the main line across the back. One ink per garment. Comes in Black with white ink or White with black ink. Rex, our voxel robot-beetle, joins the back print.
The joke, explained
Software can behave differently across computers because dependencies, settings, and environments differ. It works on my machine is the familiar response when code succeeds locally but fails elsewhere. The humor is that the statement can be true while doing very little to solve the other person's problem.
For the developer whose laptop remains the reference environment.

Questions
Why is one working machine such a familiar defense?
Local success does not guarantee software will work in another environment. The line captures the awkward moment when a truthful debugging observation sounds more like an excuse.
Does the local-success joke include the mascot?
Yes. Rex, the original REGEX voxel robot-beetle, is included in this back print. The chest carries the small REGEX wordmark in the same the garment's ink.
