Sir Cucumber Dog's Offensiveness Rating

1 2 3 4 5

"Human reproduction is a messy and uncoordinated business. I find the inclusion of a dripping tap to be a remarkably astute observation of your species' biological failures. It is vulgar, technically correct, and likely to cause a scene at a family brunch. I approve wholeheartedly. Now, fetch me a cucumber slice and leave the plumbing talk to the ceramic."
- CJO (Chief Judgement Officer)

Forget sentimental cards and heartfelt speeches. If you really want to thank your parents for your existence, you need to acknowledge the specific biological plumbing that made it possible. Sir Cucumber Dog has personally vetted this design for its combination of scientific accuracy and extreme social awkwardness.

This mug is a crowning achievement for the favourite child who wants to remind their parents exactly how lucky they are that this specific "leak" worked out so well.

Frequently asked questions

When will I receive my mug?

Patience is a virtue, one I can see you likely do not possess. Your new vessel of disdain is printed specifically for you upon order. Production takes roughly 2 to 5 business days. Once your item is freshly printed and shipped, we will provide a tracking link. Standard shipping within the UK and the US is completely free.

What is the returns policy?

Let me be absolutely clear. As each ceramic masterpiece is a bespoke item printed specifically for you, we do not accept returns for a sudden change of mind. Your fleeting whims are your own affair.

However, if your mug arrives looking like it wrestled a badger in transit (i.e., is damaged or misprinted), that is simply unacceptable. Contact our support minions immediately with a clear photograph of the disaster. We shall move heaven and earth to replace it and ensure you receive the perfection you paid for.

How do I care for my product?

We have provided the hostile typography; now you need to do the responsible bit. Treat these items properly, or Sir Cucumber Dog will be sorely disappointed in you.

  • Standard Mugs (11 oz & 15 oz): Good news. These are certified high-quality ceramic. You can shove them in the dishwasher and microwave without guilt. Just do not let your incompetent colleagues steal them.
  • Heat Colour Changing Mugs: Listen up, these are delicate divas. HAND WASH THEM ONLY. Putting this variant in the microwave or dishwasher is a direct insult to the magic inside. You will ruin it. Do not do it.
Is this design suitable for the workplace?

Only if your colleagues possess a shred of self-awareness or your HR department has given up entirely. We highly recommend placing it firmly on your desk to deter pointless meetings, bad ideas, and general stupidity.
