Ever wandered into a McDonald's on a warm summers day for some refreshing ice cream only to be told that the ice cream machine isn't working? You're not the only one. In fact, there's an entire meme that centres around McDonald's ice cream machines not working...

These are all classics, by the way. 

Too good. 

And now, the fast food joint behind everyone's favorite Twitter account, Wendy's, has got in on the action. In a reply to a tweet about Fisher-Price's McDonald's Soda Fountain, which includes an ice cream machine, Wendy's delivered this burn...

Someone needs a visit to the burn unit. This isn't the first time that the geniuses behind Wendy's Twitter account have roasted McDonald's. Here's a reply to a tweet that McDonald's corporate account probably didn't mean to send out...

And Wendy's also went on the warpath in response to McDonald's announcement back in March that quarter pounder burgers in the majority of their restaurants will be cooked with fresh beef by mid-2018. 

McDonald's just can't catch a break. Social media users seemed to enjoy this latest burn even more that those last two. 

It even made some people hungry. 

For many, the winner was clear. 

This user is even planning McDonald's funeral. 

Get these people a pay rise. 

Others were just as brutal as the red-haired girl herself. 

That's got to hurt.
