embarrassed teen accidentally uses valuable rare postage stamp

Singer:yo la tengo

he scribbled down a little note

to send news home from camp

and stuffed it in an envelope

and hunted for a stamp

his roommate had a scrapbook-full

just sitting on a shelf

he didn't think his pal would mind

so he just helped himself

he had made mistakes before

in fact

he made more than his share

but this one was a big one

because the stamp he took was rare

his roommate didn't mind it though

in fact

it made him laugh

for the stamp was worth half a grand

insured for a grand and a half
