Boston last year: A very good friend of mine did a 21 innings game 2-1 final score.
Bottom of 21st - Runners on 2nd & 3rd, 2 Outs, - B hits home run, gets half way to 1st before being mobbed, R2 runs to join in the fun R3 runs and touches HP.
The umpiring crew leave the field and hit their cars as fast as is possible!!
