Joe Biden’s sleepy performance on Monday left at least one fan ready for a nap.

As the former vice president gave a relatively brief 27-minute speech in Pittsburgh — slurring frequently and garbling words — one backer just couldn’t hold back any longer and let out a gigantic yawn.

Watch:

The man in the Firefighters for Biden union t-shirt looked relieved after the extended yawn was over .

Twitter users note the crowd seemed unenthused — and small.

Guardian reporter Mike Elk says Biden had 800 people in the Teamsters union hall, while Bernie Sanders had 4,500 in Pittsburgh two weeks ago.

Others noted the sad, lifeless faces and lack of energy on the part of supporters:

“Some were yawning others looked agitated, many wore mean mugs. It was tough to watch. You can’t manufacture excitement and enthusiasm, Especially with no new ideas and lies about a booming economy,” Rich Castaldo noted.
