Electric socket/Zombie
Me: (To employee) Do you have any Zombie birthday cards?
Employee: (Laughs)
A female customer: (Laughs loudly)
Me: My friend is called Zombie, because he falls asleep often.
A female customer: (Laughs loudly) I cannot believe you would call your friend that! (smiling)
(They had none, I bought a Bob Ross card)
(Ironically, Bob made people sleepy)
