Warning, not book related

Just something funny that I want to remember.
Scene: I am helping OlderKid with a puzzle as YoungerKid struggles to climb on to a chair, getting increasingly fussier about the endeavor moment by moment. As I walk over to help YoungerKid, OlderKid lets out an aggrieved, older-brother-esque sigh and says, "[YoungerKid], hold on to your horse." Heh.
