The title may be slightly exaggerated, but it goes well with the holiday theme! We don’t really hate these players, but boy do we envy them.
All of the Love Luck
We have multiple players reporting getting both Love Is in the Air mounts at the same time! The 
X-45 Heartbreaker comes from the 
Heart-Shaped Box while the 
Love Witch’s Sweeper is a drop from the event dungeon boss, but players are opening their boxes right after getting the broom just to show off!
One Rocket Chance Per Box?
There’s also a wider discussion about the updated tooltip for the box, as it seems to imply only the first (Warband-wide) box of the day can drop the rocket mount at all. Previously, the first drop simply had increased chances for the mount. It’s unclear whether this has been changed, but there are some ticket reports that confirm it has. But, as is pretty common in WoW, those aren’t exactly reliable information, so let’s see what Blizzard say on the matter directly.
Also, if you don’t get lucky with the broom, you can always head to the Trading Post for the recolor.
