Don't hold on to your butts -- go ahead and park them in theaters for "Jurassic World" this weekend. But before heading out, why not take 3 minutes to watch this mashup of the "Jurassic Park" franchise.

The trailer includes a good amount of footage from the Chris Pratt-led "Jurassic World," which opened today as the fourth movie in the franchise, while cleverly incorporating scenes from the rest of the series.

The first "Jurassic Park" came out way back in 1993, followed by "The Lost World: Jurassic Park" in 1997 and "Jurassic Park III" in 2001. So it's been a long time since we visited this world, and it's worth watching this scream down memory lane to relive the drama. You'd almost think by now they'd realize this whole let's-create-some-dinos thing was a bad (if entertaining) idea!
