—Feet of Clay

People performing stunts on streets (say, a One-Man Band) in order to get money from spectators, often seen at any renaissance fair. Also known as "buskers" in Ireland and parts of Canada (a word ultimately of Celtic and Iberian origin).

One common element is having a hat (or some other container) out in front in which passersby can toss money into.

Commonly an Acceptable Target in the mass media, likely to be stigmatized either as New Age Retro Hippie or "wannabe performer with no talent". However, quite a few of these artists have become successful and even world-famous.

Street Musician and Organ Grinder are Sub Tropes.

He briefly considers making money by performing Shakespearean soliloquies on the street, and we then see an Imagine Spot of Bob reenacting the "dagger scene" from Macbeth - and Comic Book Guy, assuming that he's seeing a poor imitation of a comic-book story, throwing tomatoes at Bob.

Several such characters appear around Paradise Square in the Five Points (now downtown Manhattan) in Martin Scorsese's 2002 Civil War-era epic Gangs of New York: all of them Irish, and most of them singers or fiddlers. One of them (played by folk singer Finbar Furey) temporarily takes center stage when the camera takes us inside Satan's Circus, a large tavern that is "neutral ground" for all of New York's street gangs. He appears to acknowledge our presence, and then we follow him into the tavern as he sings "New York Girls" to the accompaniment of some unseen musicians.

Literature

Discworld: Havelock Vetinari, the Patrician of Ankh-Morpork, is (in)famous for rarely, if ever, being known to have innocent people just dragged off to dungeons without a trial: The notable exception to this rule are mime artists, whom Vetinari despises. Vetinari banned all mime performances from Ankh-Morpork shortly after taking power. Mime artists who violate the ban usually find themselves hanging upside down in Vetinari's scorpion pit whilst reading a sign saying 'learn the words'. He's also said to hold Views on modern art. Notably, these are considered his good points.

Mr. Bean finally gets rid of the mime by throwing an "invisible lasso" around his waist and dragging him out of there.
