Thanks for the comment.
I thought that these (this one and the one with Sulu) were hilarious just because they were so wrong. The images are just as they were on the cartoon show, no photoshop.
The premise was that someone was playing practical jokes (I think that was the name of the episode "The Practical Joker") and did something to the replicator so people got stuff spewed on them from it.
I guess those were more innocent times, they didn't think about what it looked like, or didn't care, or did it on purpose?
