This is also the title of a silly camp or road trip song with unlimited verses. A few common ones are the following:
Oh you can't get to heaven (group repeats each line)..
on a rocking chair..
cause you'll rock and you'll rock...
and you'll never get there...
chorus:
Oh you can't get to heaven on a rocking chair cause you'll rock and you'll rock and you'll never get there, oh I aint a-gonna grieve my lord no more!
On you can't get to heaven...
on a dinosaur...
cause dinosaurs...
aren't around anymore!..
chorus
Oh you can't get to heaven...
on roller skates...
cause you'll skate right past..
them pearly gates!..
chorus
Oh you can't get to heaven...
in a submarine...
cause you'll float underneath...
St. Augustine!
chorus
Oh you can't get to heaven...
in our yellow school bus...
cause there'd be no more school...
for the rest of us!
chorus
Oh you can't get to heaven...
before I do,...
cause I'll hold you down...
so you never get through!
chorus
Etc, etc. This is the type of thing we'd just make up our own verses for, and it would never end.
