The Big Bang Theory, "The Clean Room Infiltration"
While Sheldon tends to think the act of gift giving is silly, he proved his sentimental side by surprising Amy with a gift even though they agreed not to exchange presents. Amy was touched by the token, which happened to be a talking frame featuring a picture of Sheldon sitting on Santa's lap. She then returned the favor by presenting the quirky scientist with his Memaw's cookies.
