Speaking Friday at Ivy Tech Community College, President Obama did his best to show the audience the bright side of life in Obama’s America, noting that “a lot of families are saving a lot of money at the gas pump, which is putting some smiles on folks’ faces.” That line induced giggles in the audience and elicited a “Thank you” from one attendee. Obama’s response? “You’re welcome.”

The president did warn that gas prices will go back up, and it very well might be due to a federal gas tax hike that the White House has said is on the table after all.

The president’s reference to lower gas prices did put smiles on the faces of those in the audience, though it’s possible those smiles will disappear the next time they fill up at the gas station. As Fortune reports today, gas prices spiked an average of 20 cents a gallon overnight.

Thanks, Obama!
