If you need to describe a sound via text, here's a great example of how to do it.
Continuing the "I ain't got any cash for a fancy alarm system", why not improvise? This also looks like a cast iron so this will definitely wake up everyone.
I should have went with an iPhone, it's way cheaper to get woken up randomly during the night.
Just trying to recreate the sound in words. You know, whoop whoop...
And the latest version also comes with an included scale. Apart from being abruptly awakened, now you can also be depressed about having an extra pound.
Now that's quite a brilliant invention. Hahah, gotta get one too.
Another Will Ferrel awesome moment. Hah, owning the clock!
5, 4, 3, 2, 1.... WAKE UP GIRRRRL!!! HAHAHAH
Okay, prepare for getting woke up in 5, 4, 3, 2, 1.... !!!
I dare you to stop the alarm clock, wait, I double-dare you. DON'T! YOU FOOL!
