"I Spy" lyrics

I spy with my eye something beginning with 'Th'
Oh, this is lots of fun
Yes, it's my thumb

I spy with my eye something beginning with 'B'
Oh, we'll take a look
Yes, it's a book

I spy with my eye something beginning with 'T'
Oh, my dear aunt Mabel
Yes, it's a table

I spy with my eye something beginning with 'C'
Oh, yes, fancy that
It's a cat

I spy with my eye something beginning with 'Ch'
Oh, rock-a-bye your bear
That's right, it's a chair
