My Dad was drunk one night at a wedding reception and kept on singing at the top of his lungs to Dancing Queen by Abba, but he kept singing
"Dancing Queen, eating a Chinese with Mr Bean oh yeah, you can dance in your underpants......"
Of course they were not the right words but still had people in fits of giggles.
