Why do we never make adult jokes in front of orphans?

Because the joke needs parental guidance.

I was going to tell a joke I made up about my vacuum cleaner, but it sucks.

Yo mama so fat that when she fell on the concrete, nobody laughed, but the concrete cracked up.

I told a crippled guy he is immortal because he can't kick the bucket.

A proud father has six children. He always calls his wife "mother of six" to her displeasure.

One night at a party, he yells across the room, "Mom of six, we're going now." She replies: "I'll be right there, father of four."

Help, my ADHD is so bad that not even I can focus in a concentration camp.
