Bash: The most useless command (3)

The blog statistics show, that there are many people reading the posts about useless commands. And there is the next candidate, suggested by an anonymous comment:
sl
This is my most hated program on a shell. Why?
NAME
sl − display animations aimed to correct users who accidentally enter sl instead of ls.
and this program is not interruptable by ctrl-c.
It shows a train running from the left to the right
and blocks your shell for at least 2-3 seconds (depends on the width of your shell window):
$ time sl
real 0m3.347s
