Geek / Shell humor: kill

I read about the following in a tweet I simply can not find again, but I thought it was too funny and true not to share. The following represents the input and output of a terminal, likely on Linux or similar:

~: $ happiness
happiness: command not found
~: $ love
love: command not found
~: $ kill
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

Now, why is this funny? For all non-coding people: it basically says that the kill command is the only legit to the system and that it doesn't understand love or happiness. Kill ends a process, it's a little like a hardcore task manager. I think I should write some aliases for happiness that would show how good the system is doing and throw some nice words at the user!
