Iranian President Mahmoud Ahmadinejad mocked Israeli Prime Minister Benjamin Netanyahu's bomb diagram, saying that His painting was terrible and he should work more on his drawing.

"He had drawn an infantile diagram which was more an insult to the audience and that showed how they look at others; they see themselves in a high position and (see) other nations as to be nothing," Ahmadinejad told reporters in a press conference here in Tehran today.

"That is a very hideous behavior," Ahmadinejad added, and advised Netanyahu to "do more drawing homework to improve his painting" skills, according to Fars News. 

When Netanyahu held up a cartoon-like drawing of a bomb during his speech at the UN he set off an explosion of jokes and mockery.

The Bibi Bomb, as it's being called using Netanyahu's nickname, is the latest in a series of props used by the Israeli leader as he tries to keep the global spotlight on Iran's nuclear program.

The image of Netanyahu and the diagram of a bomb with a lighted fuse was top news around the world. Headlines in Europe referred to his "bomb cartoon" and "comic strip."
