Consecutive hat-tricks against the same opponent

A question was asked on Twitter:

How many hat-tricks by the same player have been recorded in two consecutive games between the same teams in the regular season?

The question was prompted by the anniversary of this feat achieved by Brett Hull against Toronto Maple Leafs in the 1990/91 season (image courtesy of @STLBluesHistory)

So I ran a set of queries against my database and here are the results (data since 1917/18)

The number of consecutive pairs of games between two teams during a regular season: 2753
The number of such games with any hat-tricks: 460
The number of such games with hat-tricks in both of them: 34

You see how quickly the list is dwindling...
And then, the number of such games with hat-tricks by the same player in both of them: ... 3
You would think that's 3 players. It's actually two.
Babe Dye of the LeafsToronto St. Patricks did it twice!
Against Montreal Canadiens, on 1921/02/05 and 1921/02/09
Against Hamilton Bulldogs, on 1922/12/23 and 1922/12/27

Also, if we combine the last game of one regular season, and the first game of the next one, Babe Dye earns himself a hat-trick of such hat-tricks:
Against Montreal Canadiens, on 1922/03/08 and 1922/12/16

And then, 68 years later, Brett Hull earned himself yet another fantastic distinction. And he's the only one to do it on the consecutive days.

More trivia:

• The Toronto franchise is involved in all 6 (or 8) of these games.
• 3 of 6, or 5 of 8 of these games happened in its home arena.
• 5 of 6, or 7 of 8 of these games happened on Canadian soil.

If we expand that query to include playoffs, the series style of the playoffs grow the lists significantly.

The number of the consecutive pairs increases to 6348

The number of the hat-tricks in such consecutive games almost doubles to 909

And the number of hat-tricks in both of such consecutive games becomes 58

So two more players enter this venerable list:

Doug Bentley of the Chicago Black Hawks achieved this feat against the Detroit Red Wings on 1944/03/28 and 1944/03/30.

Jari Kurri of the Edmonton Oilers did that to the Chicago Black Hawks on 1985/05/14 and 1985/05/16.

Brett Hull's record will stand undisturbed at least for today (October, 25, 2019).
