I think I’d have a problem with eating half my weight in bugs, but I think I’d be completely ok with eating half my weight in steak and ice cream.  Chinny has the right idea!

Step 1 to becoming Batman: Eat bugs.
Step 2 to becoming Batman: …why did you eat bugs? Probably train to be a ninja or something… At least watch parkour videos on Youtube.
Step 3 to becoming Batman: Defeat villains.  Playing through old Megaman games totally counts.
Step 4 to becoming Batman: Get movie franchise. Batman is rich, after all.
