Irish people were left flabbergasted on couches up and down the country at what they saw and a large number expressed their approval/absolute shock at Dessie's grinding antics on social media.

Des himself took to Twitter to express his appreciation for his dance partner Karen Byrne. We reckon she must have the patience of a bloody saint.
