Okay, another thread is in danger of being hijacked by a discussion on kids' meal toys so I thought I'd start another... These are what I can remember of the US offerings...

McDonald's Batman the Animated Series (4 figures/4 vehicles/1 "under 3" figure)
Hardees DC Superheroes (Superman, Batman, Wonder Woman and Flash)
Burger King Superman the Animated Series
Taco Bell Batman Animated (animated tie-in to Batman & Robin movie)
Burger King Batman Beyond (the Inque figure is a must for collectors!)
Jack-in-the-Box DC Superheroes I
Jack-in-the-Box DC Superheroes II
Subway DC Superheroes clip-on figures
Subway Justice League (translucent Superman and Batman/Wonder Woman and Flash straws/Hawkgirl, Green Lantern and Martain Manhunter figures/JL ball "under 3" toy)
Subway Static Shock (1 figure and 3 activity toys)
Burger King Justice League
Jack-in-the-Box Justice League

...I know that there have been offerings by Quick and Jolibee and I think even Wal-Mart in Mexico has offered watches in their kids' meals. There were also balancing toys of the big 3 offered as a mail-in from Kraft... Did I miss anything?
