What happened on the way to school?

Yesterday in my final OC class with 1-2, they had to complete a dialogue on the subject of embarrassing incidents. The dialogue had to include the lines “I’m sorry………..”, “What happened?”, and “That’s too bad.” The conversation of one of my students went like this ;

A – I’m sorry I was late for school this morning!
B – It’s ok. What happened?
A – I walked, and a bird did rest-room on my head.
B – That’s too bad!

Hilarious! I was well impressed that he’d actually thought of his own idea, rather than use the examples in the text book’s ‘Tool Box’. I then asked if he meant poo!…to which he replied, “no….no…..erm….yellow water!” I taught him the word ‘urine’, chuckled, and left him to practise the pronunciation!
