"When They Were Sore"

Maybe it's just my warped guy humor, but I can't read Genesis 34:25-26 without grinning (or grimacing):

And unto Hamor and unto Shechem his son hearkened all that went out of the gate of his city; and every male was circumcised, all that went out of the gate of his city.

And it came to pass on the third day, when they were sore, that two of the sons of Jacob, Simeon and Levi, Dinah's brethren, took each man his sword, and came upon the city boldly, and slew all the males.
