in what ways can the scene in which Mr.Bumble woos Mrs. Corney be considered hurmorous?

Mr. Bumble basically "bumbles" his way into getting some action out of Mrs. Corney. Mr. Bumble, while waiting for Mrs. Corney, inventories her goods, going so far as to rifle through her drawers. Mrs. Corney returns, very flustered at having been so put out by a pauper, so Mr. Bumble gives her something sweet which we think is alcohol. Then he pretends to commiserate with her while pulling at her apron strings. It's pretty funny!
