BBC America has whipped up a promo for their series “Planet Earth” starring the cutest 4 to 7 year old kids auditioning for the role of narrator. Who needs regular series narrator David Attenborough when you’ve got this! I can’t figure out what’s more hysterical: the kids trying to pronounce Attenborough’s name or that 6 year old girl trying her darndest to apply headphones to her ears.
