In life (and in TV) there is both a time to laugh and a time to cry, but there is also a time to spoof.

For as long as there have been things in pop culture worth referencing, there have been spoofs and parodies, from the early sketch comedy shows of Sid Caesar and Carol Burnett that poked fun at pop culture classics, to special one-off episodes of more dramatic fare, like Felicity and The X-Files, that chose to offer a more lovingly-done homage.

It's not easy to properly spoof though. Too much obvious referencing can make a spoof appear heavy-handed; not enough can make a spoof almost disappear. Only some shows can find the proper mix and create a moment, a scene or in some cases an entire episode or series that truly works. The following episodes and series found that perfect mixture and made spoofs worth remembering for years to come.
