The County Music Bar, on Saltergate in Chesterfield, claim that the hot weather caused the 'O' in its name to crack and fall off, meaning that the sign outside read... well, I'm sure you can guess.
Basically the vanished vowel meant the sign read 'THE C', then a small gap, then 'UNTY BAR'.
And we all know what that looks like.
In a bid to explain and apologise for the mishap, a social media post from the pub reads: "We apologise for any offence... the heat has caused the 'O' to crack and drop off leaving us with a rather interesting new sign...
"I can confirm we are not turning into a strip club."
Sorry, drinkers of Chesterfield. Today is not your lucky day.
Posting another update, the pub added: "Don't forget you're all invited to The Great C*nty Quiz on Thursday at 8pm..."
Now visitors have called for the name to stay that way, asking the bar's owners not to fix the sign.
One wrote: "Don't u dare put that O back up this has just made ur bar 10x more popular lol."
Another agreed: "Please don't put the O back on," while a third said: "Please never fix the sign!! This is awesome!!!"
One mischievous punter commented: "I vote that we keep it that way!!! There's plenty of people who'd fit right in at the c**** bar!!"
Sometimes unfortunate changes are made to signs and it's not always a complete accident. Take the Hollywood sign as a prime example - that has been changed a few times over the years for it to read 'Hollyboob' and 'Hollyweed'.
Back in February, when the sign was changed to Hollyboob, six influencers were arrested as they attempted to make a statement after one of those arrested, Julia Rose, had her business' social media account disabled due to nudity.
Speaking to MailOnline, Julia said: "This was to show them [Facebook] that I still have a voice.
"My business for Shagmag with almost one million followers also got disabled this year due to nudity, but I'm not doing anything more than what Playboy is doing so I think they're discriminating against my accounts."
