Infinite Improbability Drive
Even faster than light or even ludicrous speed, the Infinite Improbability Drive allows the fictional ship The Heart of Gold to go anywhere, no matter how improbable. Its description from the novel from which originates, "The Hitchhiker's Guide to the Galaxy": "The Infinite Improbability Drive is a wonderful new method of crossing interstellar distances in a few seconds; without all that tedious mucking about in hyperspace. As the Improbability Drive reaches infinite improbability, it passes through every conceivable point in every conceivable universe almost simultaneously. In other words, you're never sure where you'll end up or even what species you'll be when you get there. It's therefore important to dress accordingly. The Infinite Improbability Drive was invented following research into finite improbability which was often used to break the ice at parties by making all the molecules in the hostess' undergarments leap one foot simultaneously to the left in accordance with the theory of indeterminacy. Many respectable physicists said they weren't going to stand for that sort of thing, partly because it was a debasement of science, but mostly because they didn't get invited to those sort of parties."

Would have like the entire cup with purple color. Not just the part with the slogan. It's a nice cup!
Wow! Outstanding mug! I strive to be swoogish one day
It was fantastic very good quality.
Was purchased as a gift . Very well received . Easy ordering . Arrived earlier than predicted.excellent quality. Would recommend to friends and family and will definitely order again in the future.
The mug I ordered came in perfect shape In a box obviously designed for safe shipping. Quality is beautiful and is exactly as described. Thank you!
ABSOLUTE ART WORK!!!!! This is literally the best mug in the world. My entire family has one (wife, 2 daughters, and 3 sons). I would definitely recommend and place it as a mounoment.
Hilarious, I couldn't help but burst out loud in laughter.... !!!
It understands me. this mug has treated me better than any girl i've ever dated, and every bro i've chilled in the same bed with. we've been though thick and thin, but mostly thicc. i used to be depressed, but now this mug holds my existential fears so i dont need to carry them with me. i even wrote a song about my mug: mary had a little mug, e-i-e-i-o how i wonder what you are, floppy dongs near and far, cherri had a real thicc mug, e-i-e-i-despaci-to
Great mug, 100% recommend it for all family members! Best gift I’ve ever received!!!
It was so easy to order - and I could play with the syntax of the definition to get it just right. All of this was easy. And quite soon it arrived and is perfect.

Love it!! So true!!
I love 💕 mugs ☘️! These are so lovable. Thanks! I love the urban dictionary writers too.
The printing, the Word and it's definition -- were not quite what I expected. And the same word definition ordered on two different mugs, and yet each was described / defined differently.
Augustine would love the mis-spelling It should be Augustine's Laws. A great book - every engineer, programmer, project and programme manager should read. Based on experience of Defence and Space projects, and with lots of real data to support the tongue-in-cheek advice, it really has more value than all the System Engineering books I've never read. Can't wait to get a mug.
Sickm8 it was blooming gr8 for me GF. She bloody loved it. Onya!!!! ;)

very good product, i drink my coffee out of it every single morning. a tiny little itty bitty problem i have with it though, is that every time i drink anything except for coffee out of this mug it barrates me for having bad taste. makes me very sad, honestly. i didnt know cups could talk, but appearently i have been proven wrong. i would really appreciate it if you could start double checking if your cups are possesed by melicous spirts who like to insult you! except for that, great product!!
The workmanship of the product was excellent, and packaging for your delivery of this fragile item, a coffee mug, was appropriately safe. Nice job all around. Thank you.
It's the best mug in the history of mugs.
love it
