We used to have Jersey milk cows, and yes the bulls were always a lot of fun in the paddock. Many time I jumped head first over fences and gates. Our bulls were even more fun in the stock yards when they chased the stock handlers around, jumped over the 8-foot gates and caused all the guys in the corral behind to suddenly leap out of the way. Cattle were fun to have.

A domestic animals lack of fear of man, vs a wild animal which will often run away instead is often the cause of the danger.

Scrub bulls however are the same, probably more likely to charge than water or cape buffalo.
