Lady Gaga's Telephone

Another way to understand the telephone. A song by Lady Gaga featuring Beyoncé. This is the original one, not the previous that you have seen before.

Here you have the lyrics:

[Lady Gaga]

Hello, hello, baby, you called?
I can't hear a thing
I have got no service
In the club, you say? say
?Wha-wha-what did you say, huh?
You're breakin' up on me
Sorry I cannot hear you
I'm kinda busy
Kinda busy
Kinda busy
Sorry I cannot hear you I'm kinda busy

Just a second
It's my favorite song they're gonna play
And I cannot text you with a drink in my hand, eh?
You should've made some plans with me
You knew that I was free
And now you won't stop calling me
I'm kinda busy

[Pre-Chorus:]
Stop callin'
Stop callin'
I don't wanna think anymore
I left my head and my heart on the dancefloor
Stop callin'
Stop callin'I don't wanna talk anymore
I left my head and my heart on the dancefloor

[Chorus:]
Stop telephonin' me
(Stop telephonin' me)
I'm busy(I'm busy)
Stop telephonin' me
(Stop telephonin' me)

Can call all you want but there's no one home
And you're not gonna reach my telephone
Out in the club
And I'm sipping that bubb
And you're not gonna reach my telephone
Call all you want, but there's no one home
And you're not gonna reach my telephone
Out in the club
And I'm sipping that bubb
And you're not gonna reach my telephone

[Beyonce]
Boy, the way you blowing up my phone
Won't make me leave no faster
Put my coat on faster
Leave my girls no faster
I should've left my phone at home'
Cause this is a disaste
rCalling like a collector
Sorry, I cannot answer

[Lady Gaga]
Not that I don't like youI'm just at a party
And I am sick and tired of my phone r-ringing

[Beyonce]
Sometimes I feel like I live in grand central station
Tonight I'm not takin' no calls'
Cause I'll be dancin'I'll be dancin'
I'll be dancin'Tonight I'm not takin' no calls'
Cause I'll be dancin'

[Pre-Chorus x2]
[Chorus x3]

My telephone
Ma ma ma telephone'
Cause I'm out in the club
And I'm sippin that bubb
And you're not gonna reach my telephone

(We're sorry, we're sorry
The number you have reached
Is not in service at this time
Please check the number, or try your call again)

How it's Made the Pencil

In 1795, Nicholas Jacques Conté (a French officer in Napoleon's army) patented the modern method of kiln-firing powdered graphite with clay to make pencils of any desired hardness. But, around 1560, Mr and Mrs Bernacotti had made the first blueprints for the modern, wood-encased carpentry pencil.

 

With this video you'll discover that nowadays pencils are made using a similar method.
