Have both openers ever been out first ball in a Test innings?
Also: has any cricket ground staged more than three Tests in a row?

England played three Tests - two against West Indies and one against Pakistan - successively at the biosecure Old Trafford recently • Getty Images
It's the first time England have played three successive Tests at the same ground since 1905-06, when the first three matches of their South African tour all took place at the old Wanderers ground in Johannesburg. Oddly, there was more than two months between the first and second Tests in that long-ago series.
It looks like 20 years since England last made four changes to their team for successive Tests in mid-series. In 2000, also against West Indies, they made four alterations between the first Test at Edgbaston, and the second at Lord's - and then made four more changes for the third Test at Old Trafford.
My first thought was that no one would have scored more Test runs than Don Bradman with fewer ducks, but actually that was emphatically not the case. Steve Smith has so far made 7227 runs with only four ducks, while Wally Hammond (7249 runs) and Clive Lloyd (7515) were only out for nought four times as well. Mark Taylor's 7525 runs included five ducks, including a pair in his first match as captain, while David Gower made 8231 with a Bradman-equalling seven zeroes.
The ESPNcricinfo database throws up four cases of both openers falling first ball in a Test innings - it's possible there are one or two more, from matches where we don't have full ball-by-ball details. The first one was in Christchurch in 1932-33, when England's openers Herbert Sutcliffe and Eddie Paynter both bagged golden ducks, with the New Zealand seamer Dennis Smith taking a wicket with his first ball in Tests (he never managed another one). But No. 3 Wally Hammond made up for it with 227, as England ran up 560.
The England offspinner Jim Laker famously took 19 Australian wickets in the Ashes Test at Old Trafford in 1956 (no one else has managed more than 17 in a Test). Slow left-armer Tony Lock took the other wicket - Jim Burke early in the first innings - and Ray Lindwall and Ian Johnson remained not out in the two innings. So Laker dismissed eight Aussies twice - including Neil Harvey and Ken Mackay for pairs - and the other three batsmen once each.
