Cas Tim Jan and Me

You have all heard I am sure of the three musketeers The group with the swords not the ones with the funny ears Reminds me of a joke that right here would apply There are three kinds of people I tell you no lie Those who are really quite good at math And those who are not and that's that They were the three musketeers but they were four Their math was bad not three, four and no more I hope you're all still with me, I'm not trying to be a pest I need you to follow me because at the end there's a test There is Casarah  Yeah and hurrah She is a good ma Then there is Tim You should know him He's tall and trim And  finally there is the kind hearted Jan From England she's the one with no tan Coy and demure behind her fancy fan    If you kept count that makes three Who can argue. You'd have to agree. Now we have arrived at what I am trying to say I've just joined them and I quite enjoy sword play Do you see? I am number four. I'll just walk through their door. That makes me the best, the fillet mignon It turns  out that I am frikin'  D'Artagnan.
