A tip of the hat to Glaswegian Michael M, the man behind our new favourite T-shirt range.
"Irritate pedants by wearing a t-shirt with a slightly wrong quote on it," explains the Slightly Wrong Quotes Twitter account and Tumblr.
And yes, you really can wear them - because they're all available to buy.
Marvellous. Oh, and if you like Michael's work, do check out his Slug Solos series, too. Go on, make his day.
