But that's exactly what smart as a verb means.
Edit:
No... It's been used that way since at least as far back as the 13th century. In fact it had that use before it ever meant "clever".
smart (v.)
O.E. smeortan "be painful," from W.Gmc. *smert- (cf. M.Du. smerten, Du. smarten, O.H.G. smerzan, Ger. schmerzen "to pain," originally "to bite"), from PIE base *(s)merd-, from base *(s)mer- "to rub, pound" (cf. Gk. smerdnos "terrible, dreadful," Skt. mardayati "grinds, rubs, crushes," L. mordere to bite").
smart (adj.)
late O.E. smeart "sharp, severe, stinging," related to smeortan (see smart (v.)). Meaning "quick, active, clever" is attested from c.1300, probably from the notion of "cutting" wit, words, etc.; meaning "trim in attire" first attested 1718, "ascending from the kitchen to the drawing-room c.1880." [Weekley] In ref. to devices, "behaving as though guided by intelligence" (e.g. smart bomb) first attested 1972. Smarts "good sense, intelligence," is first recorded 1968. Smart cookie is from 1948; smarty-pants first attested 1941.

You learn something everyday.
It still sounds silly though, such an irregular use of that word in modern times.
