Uh, that would be 186 THOUSAND miles per second.  Perhaps in some slow
medium....

Really way OT even for this list, but I just had to share it. Light has
been observed (under special conditions) to travel as slowly as 91 m/s
(meters per second). The phenomenon of slow light was discovered several
years ago but we don't have real-world applications yet. So the next
time some smart ass says the speed of light is 186 miles/second you can
reply, "It depends." :-)
