Do you keep your butter in the refrigerator? You do? Stop it. Stop it right this second. You're ruining your butter experience and making your toast taste like failure. Butter is a wonderful substance. Butter is not only delicious but also versatile.
In order to enjoy your butter-on-bread or butter-on-corn, however, you have to be able to spread it. And anyone who's ever pulled a cold stick of butter out of the fridge with the hopes of smearing that yummy stuff on toast knows that cold butter simply does not spread.
