Did You Know Scottish People Can't Say Purple Burglar Alarm?

If you haven't seen Scottish comedian Limmy, you need to check him out. He is a funny man that has been streaming content on the internet for quite a while. During one of his recent streams he takes e-mail questions and more from his followers. One follower threw it out there that there are certain Scottish people that can not say the phrase, "Purple burglar alarm". At first you think to yourself, while the Scottish do have a heavy accent, they are speaking English, so the phrase Purple Burglar Alarm shouldn't be too much of a challenge to them. Limmy seems to this so as well, but then even READING the question we find out the truth. Take a look (and try not to laugh)
