元ネタは、オバケのQ太郎「ハカセもいっしょに」（昭和38年少年サンデー）です。ハカセくんのおじいさんが胸の前で手を組む格好が藍しゃまと似ていたので描きました

The original gag is from the Obake no Q-Taro chapter "Hakase's going too" (Showa 38 (1963) Shonen Sunday). Hakase's grandfather's posture of joining his hands together in front of his chest was similar to that of Ran, so I drew it that way.
