What’s the best way to say “Yeah not funny”

Like whenever someone makes a joke that generally comes off as mean or weird to you or its just not funny. I dont want to simply say “not funny” because it makes me sound like a robot and I want to be able to express not only that it wasn’t funny but that it also actually wasnt in good taste. What’s the best way to say this? “Yeah not funny” i think is my best bet so far but I can’t tell if it’s an insult or not.<br><br>Edit: I’m gonna acquire this post again in a few months after my social skills get even worse and see if I can use any of the advice.
