When you host a successful game show for long enough you undoubtedly find yourself suddenly called upon to improvise all the time. Maybe it's knowing a fact about an obscure town one of your contestants is from. Maybe someone throws out an answer so off the wall you have to make a joke about it. Or, rare as this one might be, you may find yourself tasked with delivering a celebrity impersonation. That's exactly what happened to Pat Sajak in the clip below from Wheel of Fortune.
I don't know if Pat has ever actually seen an episode of Scooby-Doo. If he has, maybe it was a version from another country. Either way, his representation of Scooby-Doo's patented speech cadence is...unique.
Props to that contestant for rolling with the situation even though Pat Sajak basically just barked in his face.
