Idea for "Useless Box"... not sure how to build or what I'll need. Answered

So I got this as a gift from a friend on my birthday. I assembled it, and its great I love it.

It always brings a smile to peoples faces on around the 3rd try to turn it on lol... 

I know NOTHING about electronics what so ever just so you know, you're going to have to reply like you're talking to a second grader. 
That being said, here's my idea...

I want an LED scroll bar (like the kind that has text with a message you read as it goes across... similar to ones you would see in an airport, just tiny) with a script. Every time you hit the button on, it turns itself off, along with flashing a message. Do it again, another message. Etc... But I want the messages to go in some sort of order...

I was thinking the script could look like this:
1st Click: "You just couldn't keep your hands off, could you?"
2nd: "Much more amusing the second time, right?"
3rd: "Ok, now you know what I do... now stop."
4th: "Please... Keep your hands off."
5th: "It's starting to hurt..."
6th: etc etc etc.... for something crazy, like 100 messages...

No idea of what I need to do or how to go about it. Any guidance is welcome!!
Thanks!!!!
