Mark and Trey have a lot to talk about this week, as they reminisce over 2001. A year that had tons of landmark events, including the start of the Harry Potter and Lord of the Rings film franchises, the launch of Wikipedia, and the 9/11 attack on the World Trade Center.

Mark and Trey are taking you back to a year particularly heavy with pop culture landmarks: 1988! It was a year that truly had something for everybody. Beetlejuice was in theaters, Phantom of the Opera was on Broadway, and Dippin Dots were in food courts.

This week the boys test the limits of their time travel abilities as they go back farther than ever before: 1961! Hear about everything from the start of JFK's presidency to an actual, bonafide jetpack.

Get ready for perhaps the sexiest year in our nations history: 1998! From presidential sex scandals, to songs about sensual slow dancing, to Jack drawing Rose like one his French girls, the topic was on everyone's minds this year.

For their first holiday episode, Mark & Trey are sent back to Halloween of 1984! The country is in the throes of the Satanic Panic, murders and dismemberments are all over the news, and audiences show up in droves to watch Ghostbusters.

This week, Mark & Trey headed back to the year of America's Bicentennial! Everybody was doing something special to celebrate the U.S.'s 200th birthday, from Schoolhouse Rocky to Rocky Balboa.

Hear about the boys' trip back to 2010! A year characterized by excess: from James Cameron's Avatar to the KFC Double Down.

Today on the show, Mark and Trey relay all the pop culture landmarks of 1981! This year saw many first appearances, from the McRib, to MTV, to Jumpman (AKA Mario.)

Travel back to a time when lions were kings, tv stars were your friends, and Michael Jordan was a professional baseball player: Mark & Trey take you on a journey through 1994!

Today on the show, Mark & Trey head back to 1982: a year that was all about physical fitness, music videos, extra terrestrials, and hamburgers.
