That's what the guys at Prang Out did and now they own their own clothing brand.
We're not usually ones to promote weed culture... ahem... but we do like a good rags-to-riches story and the idea of two lads, getting stoned out of their tree, in a grotty London halls, 'trading tees for bags' and starting a business is something of a success story.
True to their roots, one of Prang Out's most popular designs is an ode to the good old king skin with various 'high grade' (ho ho ho) coloured T-shirts. Possibly not something you'd wear to meet your inlaws or on your first day at work, but a great tribute all the same.
Their 'world's first invisible tube tee' has been featured on TimeOut and others and celebrates a much loved seat pattern (see more seat patterns via one of our favourite Instagram accounts) as well as protecting you when you feel prangy on the tube.
Amongst all the stoner puns we have a fondness for this start-up brand. These are two humble guys who are just having fun being themselves; forward thinking with a love of art, fashion and good old Mary Jane.
