Ok so basically me and friends actually use to play test cricket in the late 90's during the school summer breaks because we had nothing else to do . Basically the rules were that there was no such thing as catch, runout, lbw etc.... The only way you could get a batsmen was too clean bowl his stumps. This way we actually use to get really high scores. My highest test score was 369. Basically i batted for 2 days for four hours each. so total 8 hours of batting.I didn't even count the number of balls i faced, i think it was 500 some thing
