WASHINGTON — Tensions may be high in Washington amid a stalemate in talks to raise the US debt ceiling but the White House is keeping a sense of humor.

White House officials were replying to questions on Twitter on Wednesday when a Tennessee man named David Wiggs complained that the discussion was "not nearly as entertaining as yesterday's."

The White House quickly fired off a reply to @wiggsd on its Twitter feed, @whitehouse.

"@wiggsd Sorry to hear that," the White House said. "Fiscal policy is important, but can be dry sometimes.

"Here's something more fun: tinyurl.com/y8ufsnp."

The link is to a video by pop star Rick Astley singing his 1987 chart-topper "Never Gonna Give You Up."

"Rickrolling" is an Internet phenomenon begun several years ago whereby an unwitting user who clicks on a link is directed to the video of Astley's song.

The US Treasury has warned the world's richest country will run out of cash to pay its bills come August 2, sending shockwaves through the fragile economy.
