1) The joke is told from your frame of reference which is rotating with the horse on the merry-go-round (much the same way we live on a rotating frame called earth). Within this rotating frame the elephant, kangaroo and lion are all moving at a constant speed and in the same direction as you. Therefore, to answer the question, you come to terms with all of this and drink your beer while staying on the horse.
2) While it is true, motion in a circle at a constant velocity necessarily means there is acceleration (due to changing direction), you will still travel at a constant speed proportional to the distance from the pivot as was already pointed out. However, by definition, speed is a scalar, velocity is a vector. So there was no fault in saying constant speed.
3) Anyone that answers this question in this must detail should get a one week ban from using this forum. I will punish myself accordingly. See you in a week, maybe sooner.

I am not worthy o master geek
Do we need to account for frame dragging due to the spinning mass?
