Sometimes the universe delivers comedy gold when you least expect it, and London residents got exactly that courtesy of what appears to be an epic signage fail near Waterloo and Dufferin.

The sign in question boldly warns passersby to “Beware!!! Caution Anal” – a message that’s definitely not your typical municipal advisory. Whether it’s a missing letter from “Canal” or some other bureaucratic mishap, the result has locals absolutely losing it.
The photo quickly made its way onto social media, where Londoners have been having an absolute field day with the unintentional comedy. One person quipped about the city needing “an enema first,” while another appreciated the “respectful” advance warning. The creativity of local responses has been genuinely impressive, with residents treating the whole thing with the perfect mix of humour and good-natured ribbing you’d expect from this city.
What makes this even better is how quintessentially London it feels. This is a city that’s seen its share of quirky moments, and residents have embraced this latest addition to the collection with characteristic wit. Someone noted it really “sneaks up and nips you in the butt,” while another resident declared they “didn’t see this in time” – the comedy practically writes itself.
The sign sits prominently in an area where plenty of foot traffic means maximum visibility for this accidental masterpiece. It’s the kind of thing that stops people mid-stride, prompting double takes and inevitable phone photos. One local mentioned spotting it during an evening walk, suggesting it’s been providing entertainment for multiple days.
The timing couldn’t be more perfect either, with one commenter declaring “Happy Anal August everyone!” – because apparently even the calendar is in on the joke. The whole situation has that perfect storm quality where municipal bureaucracy meets unintended comedy, creating something that’s genuinely funnier than anything you could script.
Local residents have been treating the whole thing as a community joke, with suggestions it belongs on local Instagram accounts dedicated to London’s weirder moments. The sign has achieved that rare status of being simultaneously ridiculous and surprisingly wholesome, bringing people together through shared laughter at municipal expense.
Whether this gets corrected quickly or becomes a permanent fixture remains to be seen, but for now, it’s providing exactly the kind of unexpected entertainment that makes city life interesting. The fact that it’s generated such creative responses from locals just proves that sometimes the best comedy comes from the most unexpected places.
The whole incident perfectly captures London’s personality – a city that can find humour in bureaucratic mishaps and turn a simple signage error into a community moment. The original poster noted the discussion on Reddit, where the image has sparked dozens of responses ranging from genuinely clever wordplay to appreciative observations about municipal preparedness
