and speaking of "other fun mistakes"

i've been emailing everywhere for a hotel in antigua for this weekend, for my parents and me.

i wanted to write:
mil gracias por su respuesta
(a thousand thank-yous for your answer.)

but instead just wrote:
mil gracias por su repuesto
(a thousand thank-yous for your spare.)

at least i didn't write:
a thousand thank-yous for your (part of anatomy)

or something equally as inappropriate.
