Building up a story

Grace's post:
I'm going to write a sentence and I'd like one person at a time to finish the sentence and start another one so it will become a (funny?)story. If everyone joins in, it should work and hopefully it will be funny.
The sentence is:
It was midnight and I had a craving for something to eat so I went downstairs and to my surprise......
come on guys! let's have some fun!!!!

A LITTLE DOUBT

Good morning everybody!

I have a little question: is it correct to say: “I’ll call him ON his mobile” or would it be better to use a different preposition?

Thanks to everybody.

grammar reference

- thinking of = have an idea,a opinion,to remember
- thinking about = to consider

They are both followed by the -ing form.
You can't say "I think to".



Phrasal verb: look
-look up (look up this world in the dictionary)
-look at (look at something)
-lok for (i'm looking for my pen)
-look after (take care)
-look over (to control)
