Before work i decided to chill by the telly and drink my morning coffee...in peace!! As i turn on the tv i see this commercial. It's from tv shop i think. I try and i try to swap channel, but i just dont seem to know how to do it! So i am now stuck with this guy that is trying to sell me a bloody pen that is supposed to 'remove' the scratches on your car.
Thats not the real problem though, the problem is: WHY DOES HE HAVE TO SCREAM?? I am stupid for not knowing how ro swap the channel, but i'm NOT that stupid that i dont know how to turn up the volume if i need to hear you SCREAM in My ear!! Shut up!
