They're the two Sams and if they're not quite the Two Ronnies (kids, ask your grandparents) Messrs Whitelock and Cane do a decent line in chat.
They were paired up yesterday - one hirsute and hulking, the other the boyish-looking heir to the greatest of the modern era - with the first Lions test approaching and bounced off each other neatly enough.
Big Sam the lock talked about a trip to Disneyland with his family ("His parents had told him they were going at the end of the year. Then finally it got to the week and he was pretty excited. I thought it was a good analogy," chipped in Little Sam, the flanker.)
The point is that Lions tours are so infrequent - one every four years to each of South Africa, Australia and New Zealand in turn - that they lend their own enchantment. As Whitelock pointed out, plenty of fine All Blacks never got the chance to face them.
" The hype, the atmosphere, the boys are really excited about it and that energy you can see it throughout them yesterday and today. It's something that's easy to get up for."
