Measuring 2.25" across and 1.25" high, this soft-plastic keychain features the popular expression...expressed jubilantly......by the eccentric Dr Sheldon Cooper, star of the hit, niche-culture comedy, Big Bang Theory! Yes, Dr Cooper loves to scream out, "BAZINGA," in the midst of......happiness. In the midst of....terror. In the midst of.....unruly bowels. Ahem. Yeah, so....cool keychain if you happen to like all that Big Bang theory hootin' and hollerin.'
