childish

Jokes-Tips-Advice I used to eat in my local McDonald’s all the time, but not so much anymore, not since the time I went to use their bathroom, and I saw a sign that said:
‘Employees Must Wash Hands, Especially Carl.’

Jokes-Tips-Advice Boss: “I’m sorry Mr Smith, but I’m going to have to let you go, your immaturity in the workplace has gone too far, and quite frankly you’re just plain obnoxious and childish”
Me: “I know you are but what am I?”
