Politicians are used to being interrupted when they're speaking in the House of Commons, but not by a musical tie!
Conservative MP Nadhim Zahawi was talking in parliament when his bright red tie started playing a tune.
He quickly switched it off and said sorry - he explained that he was wearing it to support the campaign against bowel cancer.
But the deputy speaker, who was in charge of the debate, didn't seem too impressed! Watch the clip to see what happened.
