The supposition that perceived humor or cleverness would be enhanced by add
ing separate content to the alternative meanings of a pun was explored, usi
ng Tom Swifties as the research vehicle. Because detecting a punning word r
elationship might induce arousal, requiring more effort and attentional res
ources for processing than noting a contextual connection, memory strength
for adverbs was also examined using a recognition procedure. Five studies w
ere conducted in which college students were asked to judge 24 Swifties (co
ntent counterbalanced across participants) in which presence of pun and con
text were manipulated. The punning relationship was primarily responsible f
or perceived humor and cleverness. Presence of a pun also enhanced memory s
trength (d') as long as the familiarization task focused on humor and cleve
rness. Coherent context enhanced perceived cleverness inconsistently. It wa
s suggested that a coherent contextual connection may make a greater contri
bution in more lengthy forms of pun-based word play, such as fables or "sha
ggy dog" stories.
