I think you're right, as I'm sure that we went about 60 games without one home and away, but THFC6061's stats don't go back that far! 04/05 we only got one and that's our lowest in the last decade apart from this season.
Two straight weeks we deserved a pen and didn't get one: handball on Barry (surely Man U, Arsenal, City and Chlesea get this) and the blatant shirt pull on Ade in Everton's penalty box. I know, they aren't usually called. To be precise, they're never called for Spurs and most other teams. They're reserved for the same four when they desperately need a pen.
