Oh, right.  And obviously anything can be implemented on top of M-x
butterfly.

,----[ C-h f butterfly RET ]
| butterfly is an interactive autoloaded Lisp function in ‘misc.el’.
| 
| (butterfly)
| 
| Use butterflies to flip the desired bit on the drive platter.
| Open hands and let the delicate wings flap once.  The disturbance
| ripples outward, changing the flow of the eddy currents in the
| upper atmosphere.  These cause momentary pockets of higher-pressure
| air to form, which act as lenses that deflect incoming cosmic rays,
| focusing them to strike the drive platter and flip the desired bit.
| You can type ‘M-x butterfly C-M-c’ to run it.  This is a permuted
| variation of ‘C-x M-c M-butterfly’ from url ‘http://xkcd.com/378/’.
