The Rajya Sabha and Lok Sabha are usually adjourned because of commotion. But on Thursday the Upper House was forced to adjourn briefly for an interesting reason -- malfunctioning of the presiding officer's seat.

The House was in the midst of a heated discussion over reports about alleged involvement of Hindu organisations in some recent bomb blasts when the problem in the seat was noticed.

Deputy Chairman K Rahman Khan, who was in the chair, rose to cool tempers. But, when he was about to sit, the back cushion seemed to fall off.

When Khan again rose to plead with the members to restore order, the Rajya Sabha staff came rushing to fix the seat.

Soon after, Khan adjourned the House for 10 minutes.

When the Rajya Sabha staff again tried to set the seat right, a witty RJD chief and Railway Minister Lalu Prasad Yadav [Images] was heard suggesting "why don't you put some bricks?"

But the problem with the seat persisted when the House reassembled at 12:45 pm and Khan adjourned it till 13:30 pm.
