"So this Kṛṣṇa consciousness movement is so nice that even people joke with us, 'Hare Kṛṣṇa,' it goes to his credit, even joking."
(Srila Prabhupada Lecture, Vrindavan, September 11, 1975)
"One who chants the holy name of the Lord is immediately freed from the reactions of unlimited sins, even if he chants indirectly [to indicate something else], jokingly, for musical entertainment, or even neglectfully. This is accepted by all the learned scholars of the scriptures."
"One may or may not know the value of chanting the Hare Kṛṣṇa mantra, but if one somehow or other chants it, he will immediately be purified, just as one who takes a potent medicine will feel its effects, regardless of whether he takes it knowingly or unknowingly."
(Śrīmad-Bhāgavatam 6.2.19, Purport)
