Do you think I should get this T-shirt?

Not that i like this T-shirt so much, but if you have a colleague sitting next to you with habit of talking to himself and if you wanna be a nice angel, guess this is the best to show him what is in your mind and ask him to shut his bloody mouth! 
 
I just don't understand why is it that he is soooooo busy... he just can't keep his mouth shut! He will either keep on talking to himself NON-STOP or he will start his humming.. He is no other than that Kanjiong Spider! I got so irritated whenever i know he will be on day shift. There's nothing i can do. I pull a long face at him whole day, I don't talk him cos i don't want him to have the impression that he has a listener and it's OK that he keeps on talking. Anyway, the fact that he does not have any audience/listener, he is still blabbering non stop! What the F***! I just can't be patient to him, really lor.. The sight of him really irritates me and his voice too! I dunno how long can i tahan, but as a colleague, i really don't wanna be that nasty, but if i have to, then that's his luck!
