This may be a stupid a question. After Old Biff gave his past self the Sports Almanac, did the past Marty that was trying to get back to 1985 just immediately ceased to exist after entering the Rich Biff Timeline?
Okay, when this episode of MAD first aired on TV, I LOVED this bit of Ben Franklin getting the Omnitrix. Would you wish Ben 10 Franklin would appear as a small cameo in future Ben 10 projects?
