Hotdog, hotdog, hot diggity dog!

Today I went out to eat with my four-year-old nephew and this was our conversation.
"Hey Aunt Tina, I gotta tell you something."
"What?" I asked.
"I gotta tell you at your home." He replied.
"What is it?" I asked again.
"It's about hotdogs." He answered.
"What about hotdogs? I asked.
"It's about another name for them." He said.
I laughed and said, "You mean wieners?"
"YEAH! Hotdogs are made out of wieners!" He yelled.
I laughed again and said "Hotdogs aren't made out of wieners they're just called wieners."
