"M is for the many things she gave me.
O is for the other things she gave me.
T is for a thousand things she gave me.
H is for the hundreds of things she gave me.
E is for everything she gave me.
R is for the rest of the things she gave me.
P is for the presents that she gave me.
Put them all together and they spell Motherp. She means everyTHING to me!"
