Ask The Rubber Duck
Have you tried explaining it to the rubber duck is the standard reply when a developer is stuck, and it refers to rubber duck debugging. The name comes from The Pragmatic Programmer (1999) by Andrew Hunt and David Thomas, which tells of a programmer who carried a rubber duck and explained the code to it line by line. Saying what the code is supposed to do usually reveals where it doesn't.
For developers who've been told to explain their code to the duck and discovered it actually works. The advice sounds ridiculous until you've tried it and found the bug halfway through the second sentence. It is slightly annoying that talking it through out loud solves the problem, and it does anyway.
More bugs that gave themselves up mid-explanation in the Bugs & Features collection.

The blank behind every t-shirt
Battle-tested comfort for uptime and off-days.
Most brands treat the blank as an afterthought. We treat it like the product it is. Every design ships on the same tee we picked after ditching the ones that pill, shrink, and go see-through by the third wash. Proper ring-spun cotton, soft enough to wear five days running, tough enough that the print still looks new long after your last deploy. True to size, no surprises. The kind of shirt you forget you are wearing, which is exactly the point.
Fits everyone
Soft ring-spun cotton
Holds up in the wash
Prints stay sharp
Great durability
Ethical and sustainable

Love it - but it was so long! Thankfully being a dab hand with a sewing machine I’ve managed to take it up to a reasonable length for the female form!
Great quality and fast delivery. Very happy with my shirt. Thanks
