Today when i logged in,
My clicking yet to begin,
Today is a fun day,
It said, "Happy Monkday!!1!"
I was welcomed with a grin.

To say it with such elation,
That's the points of exclamation,
Enclosing a number 1,
A shift, meant for fun,
The key to successful formation.

"You've been here 4 stimulating years."
The numeric pun, leaves me in tears,
(It'd be better to double,
But that's too much trouble),
The Monastery, where monks are your peers.

It warns me, "Don't panic!"
(Do they think that i'm manic?)
The greeting was cursory
It's just an anniversary
And the greeting is pleasantly organic.
