When Capcom was developing Street Fighter II they discovered an interesting bug. Originally they designed it so you could block after every attack, but apparently with perfect timing and execution you could actually link multiple attacks together and even cancel animations into guaranteed special moves on hit if you landed it just right. They decided it wouldn't be super useful because it required such extremely tight timing and executionand decided to just leave it as a hidden easter egg. Multiple hits in a row....moves chained together in some sort of....combination or something? Can you imagine?
