Starring: Chad James, Ben Singer
Mario VS Sonic (Nintendo VS Sega) - S5-E13
Revealing mistake: Except when Sonic picks up a handful and throws it in Mario's face at the start of the fight, neither character has any effect on the sandy beach around them. Sonic even runs circles around Mario at super speeds with no effect on the soft sand. (00:15:45)
Other mistake: When Shao Kahn rips M. Bison in half, M. Bison's hand is ripped apart too... and then stays attached to his body somehow.
Nightwing VS Daredevil (DC VS Marvel) - S5-E12
Nightwing: Hah, see you in Hell. (00:17:40)
