[3] Willem Sandberg invited him and Ger van Elk to exhibit in Museum Fodor; among other things, they covered one floor with broken glass and one with kitchen salt.

[4] With Willem de Ridder and others he manufactured paper installations on the VARA television show Signalement that was ridiculed in the press in December 1963,[5] and published a full-page enumeration of types of meat balls in 1965 in Vrij Nederland, already displaying his love for absurdist humor and language games that marked his later career.

Museum Boijmans Van Beuningen in Rotterdam bought the concept in 2010 and installed it in 2011;[6] at least three visitors accidentally walked onto the 4 by 12-meter floor,[7] and Schippers fielded more than 500 video questions on the blog Pindakaaspost.

The two shows were closely related (Schippers also designed the sets for both), and featured absurdist comedy which included the kinds of low-brow content not allowed to be seen or heard on Dutch television— dog poop, nudity, profanity.

Controversy arose over a skit in which Barend Servet interviewed Juliana of the Netherlands (played by "Ria"); the queen drank sherry and cleaned Brussels sprouts to pretend to feel close to the Dutch people, before throwing them in the trash or donating them to a children's home.

The show led to questions being asked in parliament about the depiction of her majesty, and the VPRO was censured by the minister of culture, narrowly escaping having its broadcasting hours cut.

[10] In the 1980s, Schippers wrote, directed, and acted in the VPRO shows De lachende scheerkwast, Opzoek naar Yolanda, and We zijn weer thuis.

Many of the word jokes and catch phrases from his television and radio shows have found their way into the Dutch language—examples cited are "Jammer maar helaas" ("Pity, but unfortunate", Jacques Plafond), "Reeds!"

[1][3] Since Going to the Dogs he has periodically returned to the stage, with Wuivend graan (2007)[14] (nominated for the Toneel Publieksprijs, an audience award),[15] Wat nu weer (2009),[16] and most recently Het laatste nippertje (2011).

Notable (and monumental) art projects of his include Torentje van Drienerlo (1979), in which the top of a tower rises above an artificial lake, suggesting the rest is underwater, and the "marriage room" in the Amsterdam Stopera (1988).
