However, his appearance at the Fire Fighters Convention was not in a completely joking manner. Biden used the time given to express his sincere thanks and appreciation to first responders for the work they do. He specifically recognized those who came to the rescue during the Colorado theatre shooting.
"They're alive, those 58 people, because of you. You arrived on the scene in a timely way, you got them the immediate help," Biden said. "Look, I think I know you guys," Biden finished. "We owe you. Every now and then, it's worthy and worth it just to remind people."
