I Drive the Kids' Bus to School is a song that Barney made up while he was driving a school bus to school. Not much to the song, except that Barney really did smoke and drink before he brought the kids to school. This song can be heard near the end of the lost Barney episode Evil Barney Bus Driver, YouTube, and it is the third song on The Evil Barney Song Soundtrack.
Barney: I drive the kids' bus to school, but first let's stop to shoot some pool. A smoke and drink while bringing you to class, and if you tell I'll kick your ass! Oh see you tomorrow kids. Bye bye!
Some versions of this song have Barney saying taking you to class rather than bringing you to class.
TVGeorginaKiwi reviewed it that it looked like Linus and Lucy was sung by Fifth Harmony.
