When these two came to the net for the pre-match flesh-press it was easier for Ivo Karlovic to pat Andy Murray on the head than shake his hand.
We are after your memories of similar sporting stature mis-matches today.
Here's one to get you started.
David Haye taking on Nikolai Valuev in 2009 - a man who would be laughably large if he was not trying to punch you in the head.

Murray v Karlovic
Andy Murray is part of a two-pronged British attack on the third round with national number two Aljaz Bedene playing world number one Novak Djokovic tomorrow.
It is only the third time in the Open era that there have been two British men into the third round of the men's singles at Roland Garros.
In 1968 there were three with Gerald Battrick, Mark Cox, Paul Hutchins. That unlikely couple of John Lloyd and Buster Mottram made the third round in 1978 and in 1999, Tim Henman and Greg Rusedski made the same stage.
Murray v Karlovic
Ivo Karlovic is the most senior gunslinger in this part of Grand Slam town for some time.
The 37-year-old is the oldest man to make the third round of the one of the calendar's big four events since 39-year-old wildcard Jimmy Connors went all the way to the last four of the 1991 US Open.
BBC Radio 5 live sports extra
As Andy Murray strides out onto Suzanne Lenglen and is helpfully told by the umpire that this is a best-of-five sets match, BBC Radio 5 live sports extra commentary begins.
This is an online-only bit of audio you lucky people, so click at the top of this page to get it fresh and live to your ears.
Sixth seed Simona Halep has just survived a close-ish shave against 18-year-old world number 101 Naomi Osaka.
Halep recovered from the loss of the first set to win 4-6 6-2 6-3 and progress to the fourth round.
But all the post-match chat is around what sparkling future might await the big-hitting Osaka.
Murray v Karlovic
If you want to recreate the size of the challenge that Andy Murray is facing against six-foot-11-inch Ivo Karlovic, that's your template.
The Croat leads the ATP's service stats for the year, averaging a whopping 23 aces a match and winning nearly 95% of his service games., external
Fortunately Andy Murray is one of the game's best returners.
Even so, I'd bank on a few tie-breaks.
