Temporary fence HR or Ground rule double?

[MD Longhorn]

Hey, if we're going to use only single lines in the rulebook and ignore the rest of it, the following are home runs too...

26. HOME RUNS / FOUR BASE AWARDS / GROUND RUlE DOUBlES.
When a ball does not hit the ground and leaves the playing field in fair territory, it is a home run.

1) Outfielder catches the ball and throws it to a fan. (The ball did not hit the ground and left the playing field in fair territory.)
2) Fly ball ricochets off the concrete base of the flag at Minute Maid park and bounces over the fence.
3) Ball caught in stand in foul ground. Fan throws it back fair and over the outfield fence. (The ball did not hit the ground, and while it did initially leave the playing field in foul territory, it then reentered and left the playing field in fair territory).
4) Ball lands squarely on a discarded empty box of popcorn in left field and bounces over the fence.
