It's called riding the goat
Here is a sample text of a goat riding initiation and how it was used in the Lodge:

The Goat is usually the first "stunt" introduced to a candidate; he is hoodwinked in ante-room and when he enters the Lodge room he is picked up and placed on the Goat and given a ride several times around the Lodge room and dismounted in front of the Chief Officer's Station, where he is presented for instructions.



A NOVEL WAY TO INTRODUCE THE GOAT.

The candidate is hoodwinked in the ante-room and conducted to the Chief Officer's Station.

CONDUCTOR - "Chief Officer, I present you Mr. Who is a candidate seeking the mysteries of our Order. He awaits your instructions."

OFFICER-"My friend, before permitting you to advance into this grand and noble Order, it is my duty to examine you by asking you certain questions, for your answers, which will be considered by the Lodge before starting you on your journey to seek the secrets of our Order."

"What is your name in full?"

"How old are you?"

"Are you single or married?"

(If married) "How many children have you?"

"What is your occupation?"

"Have you always been able to earn a good livelihood?"

"Do you consider yourself to be sound and in good health?"

"Have you a good appetite?"

"Do you eat meat?"

"Do you like butter?"

"Do you like soft or hard butter?"

(Candidate will say hard butter.)

"Very well, we will try and satisfy your appetite. We have the hardest and best butter in this section of the country. This butter has been tried by every candidate introduced, and they can all testify that he is a hard butter. Attendants, bring forth Billie, our hard butter, and administer some of his good qualities to our candidate."

(The Goat is brought in and the candidate is mounted and given a ride around the Lodge room, and finally returned and dismounted in front of Officer's Station, and the following is introduced if desired:)

OFFICER-"Well, sir, how do you like our butter?"

(Candidate is liable to say it's all right.)

OFFICER-"Now, my friend, you said, I believe, that you liked meat any old way. I am glad to know that you do, because we have an obligation in the way of a meat test which I will have to administer to you."


No big deal, just some fun Mason's have.
