Whee! The highest number of runs scored in an over is not 36. Not even double that figure. It is only a mere 77 runs. Wow! How silly a bowler that could have been? It is all true apparently. One over in the history of first class cricket has recorded a whopping 77 runs. Check this out for a detailed run through story.
This is the scoring pattern (Much like a UK telephone number including the ISD code!): 0444664614106666600401. Even more striking thing is that, some dot balls figured out in between. Those were the times when batsmen got bored by hitting anything not too cosy for them!
