When I made my granny's salad, I added psychedelic mushrooms.
That's awful. What would make you drug your granny like that?
I knew she was eating salad on Thursday, so it was an easy target for me.
Spiking someone's food or drink is dangerous and unethical. If you want to prank someone, find something that doesn't do harm or damage to the victim.
What do you know, this was a great prank. Granny got fucked up, god damn. I should do it again.
No you shouldn't, it was good that nothing really bad happened this time but something could happen next time. It is also illegal to mess with another person's food by drugging them.
