Srimad Bhagavatam Canto 10, Chapter 11, Text 08

SB 10.11.8

bibharti kvacid ajñaptah
pithakonmana-padukam
bahu-ksepam ca kurute
svanam ca pritim avahan
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sometimes mother Yasoda and her gopi friends would tell Krsna, “Bring this article” or “Bring that article.” Sometimes they would order Him to bring a wooden plank, wooden shoes or a wooden measuring pot, and Krsna, when thus ordered by the mothers, would try to bring them. Sometimes, however, as if unable to raise these things, He would touch them and stand there. Just to invite the pleasure of His relatives, He would strike His body with His arms to show that He had sufficient strength.
