Warning: if you are very sensitive, this may not be the post for you. On the other hand, if you are curious what it sounds like when I try to sing (spoiler alert: not good), this may be just the post you are looking for.
Often when I'm walking with my kids and dog, we (okay, I) sing songs about what we see. Here is one example (no pictures of the deceased amphibian, I promise).
Lyrics (for those of you who want to know, but can't listen because there's a baby sleeping on your lap or something):
Dead frog in the middle of the road!
Dead frog (or possibly a toad)
Ribbit. Ribbit. CROAK.
