The Fairly OddParents S09E23 - Turning Into Turner

Mr. Crocker tries to transform into Timmy with his DNA replicator, the "Turner-Me-Into-Turner-Ator", but due to his mom's spit DNA on a gum with Timmy's DNA, he transforms into a fusion of Timmy Turner and his mom. Then after he looked at himself in the mirror, he pretends to be Timmy from the "future".
