President Obama apparently doesn't like to be kept waiting.
But, he ended up waiting quite a while for his friend, former president Bill Clinton, to board air force one.
Finally, Mr. Obama yells "come on" to Clinton.
Once Clinton climbed the stairs, the two men shook hands and patted each other on the back.
The two were in Israel for the funeral of former Israeli Prime minister Shimon Peres who died on Wednesday.
