George Bush, Queen Elizabeth, and Vladimir Putin all die and go to hell.  While there, they spy a red phone and ask what the phone is for.  The devil tells them it is for calling back to Earth. 
Putin asks to call Russia and talks for 5 minutes.  When he is finished the devil informs him that the cost is a million rubles, so Putin writes him a check. 
Next Queen Elizabeth calls England and talks for 30 minutes.   When she is finished the devil informs her that the cost is 6 million pounds, so she writes him a check. 
Finally George Bush gets his turn and talks for 4 hours.   When he is finished the devil informs him that the cost is $5.00. 
When Putin hears this he goes ballistic and asks the devil why Bush got to call the USA  so cheaply. 
The devil smiles and replies: "Since Obama took over, the country has gone to hell, so it's a local call."
