As children we are shown to make a wish then try to blow ALL the dandelion seeds off at once so it can come true. As adults we don't want any of those seeds spreading through our beautiful lawns!
As many of you already know, Dandelions are a pest to a lawn due to "They aggressively compete with grass and ornamental plants for sunlight, water and nutrients. Dandelions are perennial weeds that reproduce seedlings rapidly during the spring and fall seasons. Once established, they continue to appear unless eliminated."Read more:

And eliminating dandelions is also a pesky thing to do- According to landscaping.about.com at
http://landscaping.about.com/od/weedsdiseases/a/kill_dandelions.htm "Above-ground, their seeds ride the wind currents, poised to drop into the slightest opening in your lawn to propagate the species. Meanwhile, below-ground, they strike down a taproot up to 10" long. Pulling the taproot as a means of dandelion removal is problematic. Thick but brittle, the taproot easily fractures -- and any fraction of the taproot that remains in the ground will regenerate." This means that dandelion wishes made with the natural wind, and the regrowth of dandelion roots that are attempted at being picked, make these annoying weeds difficult to get rid of.
According to
www.richsoil.com, "
Dandelions love a pH of about 7.5. Grass loves a pH
of about 6.5. So if your pH is 7.5 or higher, your grass will probably never
beat out the dandelion. Lower the pH to 6.5 and your grass has the
advantage!" So pH levels can help... what else?
As
www.better-lawn-care.com states, there are some organic ways:
The best time to attack them is right after they flower - when they have finished blooming, not when flowers are present - they are weakened by low food reserves in their roots. Dandelions flower in the spring and again in the fall.
You can control them by pulling or digging. Make sure the soil is moist and remove as much of the taproot as possible. Weeding tools - like the Weed Twister, Weed Hound or a large flat-head screwdriver - are helpful. You will probably have to dig a dandelion several times before it is eliminated. Keep digging the new plants as they return and before they form a large taproot.
Horticultural vinegar (20% acetic acid) can be used to spot spray dandelions. Kitchen grade vinegar is not an effective herbicide, its acetic acid concentration is only 5%. The acetic acid concentration needs to be at least 20% to be an effective natural organic weed control. Vinegar will only kill dandelion foliage - not the taproot - new plants will return from the taproot. Vinegar is also non-selective, take care to spray only weed foliage because it will kill any foliage that you spray - including your grass!
Corn Gluten Meal can sometimes be used as natural organic weed and feed. It has been observed to work as a pre-emergent herbicide - it prevents seedlings from developing a root system - it will not kill mature dandelions. Just be aware that CGM can be difficult to use as an herbicide - timing and environmental conditions must be perfect for it to work. It is 10% nitrogen by weight - making it a good natural organic fertilizer.

And of course, there is the option of using chemical removers and herbicides-as long as they are the right ones, done in the right way, and at the right time.
