"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."
