What do you call an epileptic being attacked? A salt shaker
This is a kind of messed up joke man!
No, I just find it funny that the other person shakes when they get epilepsy
Making fun of someone who is epileptic shaking is kind of insensitive. I would assume that anyone who is epileptic would not enjoy when something like this happens to them. For this reason, it would be the mature thing to not make light of the situation.
Don't get mad at me just because I'm being funny.
But you're not being funny. The joke isn't clever or witty. You're just using offensiveness to try to be funny.
