I Know You Are But What Am I Pee-Wee Herman T-Shirt

With a hit movie, a Saturday morning TV show, and most importantly, a childish sense of humor, Pee-Wee Herman became one of the most iconic characters of the 1980s. Pee-Wee was always ready to entertain audiences with his signature laugh and his catchphrase "I know you are but what am I?"

This 80sTees.com exclusive Pee-Wee Herman t-shirt features Pee-Wee's catchphrase and his trademark bow tie. Pee-Wee most famously used his phrase against Francis in Pee-Wee's Big Adventure when Pee-Wee refused to sell his bicycle, and Francis called him crazy, a nerd, and an idiot.

For any fan of the wacky, nutty, cuckoo Pee-Wee, this I Know You Are But What Am I Pee-Wee Herman T-Shirt is a must have!
