[Grammar] Regarding the use of preposition at

[Joe333]

Sentence: "Here is the link where Jon Stewart of CNN japed at X and Y." ( X and Y are names of certain people which I don't want to name for some reasons)

My question: Should the above mentioned sentence contain preposition at or any other preposition ? Or it would would do without it and other preposition ?

**My own sense is there is no need of preposition at or any other preposition in the sentence but I'm not sure about it which is why I am seeking your help. So forum members kindly help me

Thanks

My question: Should the above mentioned sentence contain the preposition "at" or any other preposition there?

If "japed" means 'mocked'/'made fun of', you should not use a preposition.
