I am quite familiar with the verbs. Thanks.

My original joke was based on the assumption that "She lay" was intended to be in the present tense (and why wouldn't it be?) and therefore a humorous use of colloquial English (in place of "she lays", possibly invoking African American English for humorous effect. We can argue about whether this is culturally sensitive.). The corresponding correction would therefore be "She lie", rather than the grammatically standard "She lies".
