You'd be surprised

Hes not so good in a crowd
But when you get him alone,
Youd be surprised.
He isnt much at a dance
But then when he takes you home,
Youd be surprised.
He doesnt look like much of a lover,
But dont judge a book by its cover.
Hes got the face of an angel but,
Theres a devil in his eye.
Hes such a delicate thing
But when he starts to squeeze,
Youd be surprised.
He dosnt look very strong
But when you sit on his knees,
Youd be surprised.
At a party or at a ball,
Ive got to admit hes nothing at all,
But in an easy chair,
Youd be surprised
