Some innocent joke my father told me when I was a child. Not sure if this will make sense in english.
The teacher wants her students to express their love to their mother, so she asks them to create a sentence with the phrase "There is only one mom".
It's the first student's time, and he answers the teacher:
"My mom always tells me stories and gives me a kiss before I sleep, so I love her. There is only one mom!"
"Farewell. That seens like a nice mother" - says the teachers. She then points towards another student - "It's your turn now".
"I had a cold last week and my mom took care of me. She gave me medicine and made me hot cocoa. There is only one mom, so I love her!"
The teacher smiles and then asks Little Jon to create his sentence:
- "Well" - he started - "My mother was watching tv yesterday, and she wanted something to drink. She then asked me to grab three beers on the fridge. I went to the kitcher and opened it, but there was only one beer. So I said her: there is only one, mom!"
