SB 10.15.4
sa tatra tatraruna-pallava-sriya
phala-prasunoru-bharena padayoh
sprsac chikhan viksya vanaspatin muda
smayann ivahagra-jam adi-purusah
Translation:
The primeval Lord saw that the stately trees, with their beautiful reddish buds and their heavy burden of fruits and flowers, were bending down to touch His feet with the tips of their branches. Thus He smiled gently and addressed His elder brother.
Purport:
The words muda smayann iva indicate that Lord Krsna was in a joking mood. He knew that the trees were actually bowing down to worship Him. But in the following verse the Lord, speaking in a friendly, lighthearted mood, gives the credit to His brother, Balarama.
