Robert A. Heinlein Quote

Never attempt to teach a pig to sing; it wastes your time and annoys the pig.


TimeEnough for Love (1973)


Never attempt to teach a pig to sing; it wastes your time and annoys the pig.

Never attempt to teach a pig to sing; it wastes your time and annoys the pig.

Never attempt to teach a pig to sing; it wastes your time and annoys the pig.

Never attempt to teach a pig to sing; it wastes your time and annoys the pig.
