Watch 'Broad City' Stars Rip the 'Time Traveling Bong' in New Trailer

Ilana Glazer, Paul Downs journey through the past and future in outrageous 4/20 special

'Broad City' stars Ilana Glazer and Paul Downs get ripped across the space-time continuum in the first trailer for 'Time Traveling Bong.'

Broad City's Ilana Glazer and Paul Downs — aka Soulstice trainer Trey, aka Kirk Steele — blaze across the space-time continuum in the outrageous trailer for their upcoming 4/20 special, Time Traveling Bong.

Like a certain hot tub before it, Time Traveling Bong centers around an oddly specific time travel device that sends Glazer and Downs, as hapless stoners Sharee and Jeff, into the past with one puff and back to the present with another. Of course, things don't go so smoothly after a Puritan smashes their pipe upon their arrival in colonial times.

As Sharee explains in a hilarious, breathless voiceover, with the structure of the bong compromised, the pair are forced to travel erratically through time. The clip highlights trips to ancient Rome, Fifties America and prehistoric times, during which the pair fail miserably at doing anything that might alter the future. 

"Who are we to say what history should and shouldn't be?" Jeff asks. "Not us — we are idiots!" Sharee cracks in return.

Time Traveling Bong is based on a sketch Glazer created for College Humor in 2012 that also co-starred Downs. The new special will air over three nights, starting April 20th, on Comedy Central.
