This bull mated 339 times last year

The cattle farmer always makes two trips to the stockyard per week, his wife never goes until
today. Today he's in search for a new bull. As they start down the first row of bulls a sign on the
first pen says "This bull mated 35 times last year."

The wife says, "look honey that's good?" The farmer says, "that's nothin".

The next pen's sign says "This bull mated 148 times last year." The wife says, " I know that's good!
"The farmer says, "oh, 'bout average,,, I need the best."

The last pen has a huge bull and the sign says "This bull mated 339 times last year" The wife says
"Oh, look honey that's what I need from you! The farmer says, "sure baby I understand all that, but
there is one thing the sign didn't say."

She asks, "Whats that?"

"It didn't say it was 339 times with the same COW!"
