Graeme McDowell was as cool and calm when he appeared on the iconic Tonight Show with Jay Leno as he was when capturing his first major at Pebble Beach.

Dressed in jeans and a casual shirt, he never put a foot wrong on the biggest chat show in American TV history.

Leno cracked a series of jokes about beer drinking Irishmen but McDowell played along for laughs and went down well with the live TV audience.
