The BBC turns 100 today, and its rival broadcaster Channel 4 couldn't resist sending a cheeky birthday message.
Many found Channel 4's birthday jibe hilarious, as it pointed out that despite a century passing, some things are remarkably similar in the UK.
The Channel 4 official Twitter account posted: "[celebration emoji] Happy Birthday @BBC on your 100th birthday! When you were founded we had a King, no one knew if they could afford to put their heating on and we'd just lived through a global pandemic. Times really do change!"
The tweet has racked up more than 54,000 likes and 500 quote Tweets.
Sharing the Tweet, one person said: "Magnificent! Ch4 ahead and up to times yet again :)".
Another wrote: "Channel 4 always slays." A third person said: "@Channel4 delivering All of the Spice!!!" Another simply said: "Incredible".
To mark 100 years of the broadcaster, Strictly Come Dancing will be holding a BBC themed episode.
This Saturday, dancers will be moving and grooving to the likes of the Casualty theme song as well as the Grange Hill theme song.
