One evening, a phone call

One evening, Barack Obama gets a phone call at his home. He answers, "Hello?"

"Hello Barack," comes the reply. "This is President Trump. I need your help."

"Donald, this is a surprise," Obama says. "How can I help you?"

"I have a huge mess in the Oval Office," Trump explains. "I started putting together a jigsaw puzzle, and I can't get it. There are thousands of pieces all over the floor."

"Jigsaw puzzle?" asks Obama. "What's it supposed to look like?"

"The picture on the box is a rooster," Trump replies. "This is very embarrassing. Please come over and help me."

Obama gets into a cab and heads to the White House. He enters the Oval Office, takes a look around, and says:

"Donald... these are cornflakes."
