Not particularly: Jupiter and Saturn rotate more rapidly.
neptune's axis is my butt
Neptune takes 16 hours, 6 minutes and 36 seconds to rotate once on its axis. That's about 2/3rds of an Earth Day. Note that the period of rotation is measured by watching Neptune's magnetic field. The time cited is the time it takes the "whole planet" to rotate once on its axis. This is important because Neptune is not solid - it's a big gas planet, and the atmosphere is rotating at different speeds.
rotating on a fixed point
You perhaps refer to the "tilt" of the axis. Neptune has an spin axis tilted at about 28.3 degrees from the perpendicular to its orbit.
Jupiter rotates on its axis most rapidly out of all eight of the planets, 9h 55m 30s for one full spin.

Neptune and Pluto
Neptune has an axial tilt of 28.32°
Any object that rotates has a tendency to continue rotating.
Then the world would have no days or nights. We would just be either day or night depending on when the earth stopped rotating on it axis.
It takes roughly 6.4 Earth days for Neptune to rotate on it's axis.
