I think it would be something like this, but in whatever language you're using to write TG2:
First time pressed: "Hello, Button 9 at your service."
Second time: "I don't really do anything.
Third: "Stop it!"
4, 5, 6, 7, 8, 9 times select a random phrase such as "Ouch!" or "Stop pressing me!"
10th time say "I QUIT!!!" or similar phrase selected randomly
<don't do anything for the next 35 minutes, only 10 presses at a time>
From then on, first time: "Why do you keep bothering me?!"
Second time: "Get outta here!"
3, 4, 5, 6, 7, 8, 9: select another random phrase
10: "I'm outta here!" or another similar phrase selected at random
Eventually, after 40 times (total) say (now this is up to you, but I'm suggesting:) "All right, I give up. The cake is a lie." Repeat every 40 presses.
