(Little Sheldon finishes his first video game...)

Sheldon Cooper (narration): Since that night, I've battled orcs, zombies, Na*zis, Na*zi-zombies, a dinosaur in a go-kart, and played Van Halen's "Hot for Teacher" on a stringless, plastic guitar. But nothing would ever compare to that first quest with my meemaw. Although Leonard pulling a groin muscle doing Dance Dance Revolution was a close second.
