RYAN Reynolds gave his friend and Wrexham AFC co-owner the perfect birthday gift by teaching the world how to pronounce his surname.

The Deadpool actor posted the video on Twitter on the occasion Rob's 44th birthday.

In the 11 second video the Canadian superstar says "McElhenney" twice.

He then looks uncertain and asks "Close?"

So know we all know how to say McElhenney...sort of.

Rob McElhenney (hope you're saying it right) turned 44 on Wednesday, April 14.

He and Ryan took over Wrexham AFC earlier this year.

He is best known for portraying Ronald "Mac" McDonald in the comedy series It's Always Sunny in Philadelphia, which he created, co-writes, and produces.

Rob is married to It's Always Sunny co-star Kaitlin Olson and the couple have two sons.
