utility knock-knock joke

Any of several well-known "door-tap pun" verbal exchanges which involve either an offer ("Howard", "Tijuana", etc.) or a request ("Woodrow", "Kudu", etc.) by da speaker to da listener; often, said query is proffered in said manner in an effort to lighten da mood and add a little humor to said proposal, in order to hopefully take some of da sting outta da expressed idea, which might involve less-than-desirable aspects such as difficult/yucky/tedious labor, significant changes in habits/lifestyle such as being more active and/or giving up "comfort" foods, etc.

A lot of da utility knock-knock joke selections are somewhat "interchangeable" as far as their "request" or "offer" status --- i.e., a word dat's mostly intended for proposing an assistive/generosity action by da speaker to da listener (such as "Howard you like me to _?", or "Tijnana do/have _?") can also be used by da speaker for asking for assistance/charity from da listener (such as, "Howard you feel about doing _?", or "Tijuana volunteer to _?"). Or by da same token, a gigglingly-uttered conversing dat uses a word which is usually reserved for giving-of-time/resources appeals can also be used by da speaker to extend an offer of help to da listener, such as, "Woodrow like me to _?", or "Kudu let me help you out by _?"
