I went to a 711 and asked for a 2x4 and a box of 3x5's. Theclerk said, tenfour.

Summary

This quote is a humorously worded interaction between the speaker and a convenience store clerk. The speaker goes to a 711 store and requests a "2x4" (a type of lumber) and a "box of 3x5's" (presumably referring to index cards or some other 3x5 inch items). The clever clerk responds with "tenfour," which is a play on words, utilizing a radio lingo term ("ten-four") that means "message received" or "affirmative." The exchange highlights the disconnect and confusion caused by using dimensional terms commonly associated with measurements in an unusual context.
