Irish rugby star Peter Stringer sees the funny side after hilarious Twitter gaff mixes him up with Paul O’Connell

TODAY is Ireland and Munster Rugby legend Peter Stringer’s 39^th birthday – but one birthday message is standing out from the rest.

The Press Association Sport Twitter account made a gaff this morning after they wished Stringer a happy 39^th – only to mistake him for former teammate and bald-headed comrade Paul O’Connell.

The post, accompanied with a picture of former Ireland skipper O’Connell, read: “Happy birthday @stringer9 – Sale’s former Ireland scrum-half is 39 today.”

Stringer made 98 caps for Ireland in a memorable career which saw him achieve grand slam success in green in 2009.

The diminutive scrum-half still plies his trade in the Premiership for Sale Sharks despite being of an age when most in his position have long since retired.

O’Connell bowed out earlier this year after suffering a career ending injury during the Rugby World Cup, despite just signing for French champions Toulon.

The pair might share a similar haircut, but that’s about where the similarities between the two end. At 6ft 6 O'Connell towers over a 5ft 7 Stringer.

Peter Stringer was quick to see the funny side of the mistake, and poked fun on Twitter at his former teammate with whom he won two Heineken Cups for Munster.

“Wow, I’ve aged terribly overnight @Paul_OConnell,” he said.

O’Connell made headlines recently after he pulled off possibly the greatest ever moment on BBC Question of Sport quiz show.
