An old joke.
Stalin's office.
The phone rings.
The secretary picks up the phone, listens and says to Stalin:
- Comrade Stalin - Churchill is calling you!
Stalin picks up the phone and answers Churchill:
- Yes!
- No!
- No!
- No!
...
- No!
The secretary could not resist and asked:
- Comrade Stalin - what question did you answer Yes!
- Churchill asked - do I hear him well?
