Dexter's Lab

"Enter at your own peril
Past the vaulted door
Where impossible things may happen
That the world's never seen before!
In Dexter's laboratory
Lives the smartest boy
You've ever seen,
But Dee-Dee blows his experiments
To smithereens!
There is doom and gloom while things go boom...
In Dexter's lab!"

One of my favorite cartoons. Mr. Tartakovsky has an amazing sense of comedic timing.
Done at Otakon.
