I remember there was a song some classmates made up to remember the non-1-dan verb conjugations that goes something like the tune of Santa Claus is Coming to Town

u tsu ru tte (You better watch out)
mu bu nu nde (You better not cry)
su shite (You better not pout)
ku ite (I'm telling)
gu ide (You why)

kuru kite (Santa claus is)
suru shite (coming)
iku itte (to town)
