Grumpy cartoon grandpa: Oliver

Grumpy cartoon grandpa, cantankerous, sputtering, and mush inside

Prompt: A creaky, sputtering old male cartoon voice powered entirely by complaints and love badly disguised as complaints. His reedy, wobbling register lurches between grumbles, indignant squawks, and long nostalgic rambles that begin with 'back in MY day.' Dentures whistle faintly on S sounds; harrumphs punctuate everything. The crankiness is theater—slip him a grandkid's drawing and the whole gruff act melts audibly.

Script: Flying skateboards! Back in my day we walked uphill to school, both ways, through a blizzard of bees! Harumph. What's that, sprout? You made this for... for me? Whoa. Don't just stand there letting the dust get in my eyes! Come here, you little rascal!
