Mujibar was trying to enter Britain legally through Immigration.

The Immigration Officer said to him, "Mujibar, you have passed all the tests, except one. Unless you pass it you cannot enter Britain."
Mujibar replied, "I am ready."

The officer said, "I want you to make a sentence up using the words yellow, pink and green."

Mujibar thought for a few minutes then said, "Mister Officer, I am ready."

"Then proceed." said the officer

Mujibar began. "The telephone goes green, green, green, I pink it up, and say, yellow, this is Mujibar.'"

Mujibar now works at a call centre near you.
