An Irish theater company, The Performance Corporation, has claimed credit for a 'flash mob' of Valentine's Day kissers who descended on the White House yesterday.

One hundred couples locked lips in a lengthy smooching session right outside the Obama residence to the amazement of passers-by on Pennsylvania Avenue yesterday evening.

It has emerged that the romantic 'Kiss USA' project was the work of a Clare,Gilda">Kildare-based theater company, The Performance Corporation.

Last year the company brought Dublin's Dame Street to a standstill with an impromptu ceili outside the Central Bank.
