My first is a creature whose breeding is unclear. My second, a price you must pay. My whole can be found in the river of Time and refers to events of today. What am I?
New bull at farm
Three bulls were standing around the farm yard one day, talking about how the farmer had just bought a new bull.
The first bull, the biggest and strongest of the group, says "He's in for a surprise when he gets here. I'll be damned if he thinks he can take any of my 500 cows."
The second bull chimes in, "I know that's right. He's not touching any of my 250 cows."
The third bull, the youngest of the bunch, pipes up and says "I've only been here a year, I know I'm not as big and strong as you guys but I've earned my 10 cows and he's not getting a single one!"
About this time, a large truck pulling a trailer backs in to the ranch and begins to unload a 4,000 pound monster of a bull. He is so big that the steel ramp is bending with every step he takes.
The youngest bull begins huffing and grunting and scraping the ground with his foot. The oldest bull looks at him and says "Son, use your head. Give up a few cows and live to tell about it."
The youngest bull replies "Hell, he can have all of my cows, I'm just making sure he knows I'm a bull!"
