Break out Looney Tunes T-Shirt: What's Up, Doc? in red soft-style cotton — officially licensed Looney Tunes merchandise carrying the Bugs Bunny What's Up, Doc? catchphrase.

What's Up, Doc? is Bugs Bunny's signature line, first delivered in the 1940 Tex Avery-directed A Wild Hare that formalised the character and cadence out of the earlier Happy Rabbit prototypes. Mel Blanc's Brooklyn-Bronx voicing did the rest; the line has stayed the Looney Tunes calling card through eighty-plus years of Warner Bros. shorts, features, and merchandise.

Standard unisex short-sleeve fit in red soft-style cotton, sized Small through XX-Large. Front print with a plain back. Wash cold, inside-out.
