You might think that having a silent co-host is every performers dream, and it's certainly worked out for magicians Penn and Teller.
They're celebrating 40 years together, and now they're bringing their long running Las Vegas show to Britain.
Next month the duo will be making magic on their first ever UK tour.
On BBC Breakfast they performed a trick with playing cards and muffins.
