Source (news article): Russian Comedians Fess Up to Pranking Elton John by Pretending to Be Vladimir Putin
“We just couldn’t pass up this opportunity to see what Elton John would say if he thought he was really speaking to Putin,” Krasnov, who played Putin, said in a telephone interview.
The voice of Putin in recording does not much resemble the real Putin; Krasnov said he had not tried to imitate Putin much because he knew Elton John would probably not be able to tell the difference since he was speaking Russian.
“I don’t have much experience in this, so I wasn’t able to joke with my position,” Krasnov said.
What exactly does he mean by saying he wasn't able to joke with his position?
