While President Barack Obama delivered a speech on nuclear reductions at the iconic Brandenburg Gate on Wednesday, things got a little hot -- literally.

Obama thanked the people of Germany for the "extraordinarily warm welcome" on the 92-degree day.

"In fact, it's so warm, and I feel so good, that I'm actually going to take off my jacket," Obama said. "And anybody else who wants to, feel free to."

The president then proceeded to remove his jacket to an eruption of applause.

"We can be a little more informal among friends," Obama said.

This wasn't the first time Obama spoke to a receptive German crowd. In 2008, nearly 200,000 people gathered to hear then-Senator Obama deliver an address as the Democratic presidential candidate.
