<human>: Could you distill the essence of the text into 1-3 sentences?

Ok so my girlfriend has been telling me that she's going to prank me today, but I've come up with my own idea and was wondering if I could get in a lot of trouble for it. 

So, I'm considering puting her number on craigslist with an ad saying something like "45 inch LEDTV FREE" and then some BS story about how my (fake) son got a DUI last night and as punishment we are giving away his TV. Then have her freak out as her phone gets blown up with texts about a free LEDTV that she has no idea about. 

Now my girlfriend is a really good sport but in the past has taken her pranks waaaay to far before. I'm pretty sure when I tell her it was me she'll think its hilarious, thats just her sense of humor. I was wondering if you guys think this is a bad idea, not only for our relationship but legally. It's not anything sexual or really personal like her address (which from my googling tells me are the most common legal issues with a prank like this) so I don't see it getting me screwed over in the end. 

What do you guys think? Hell yeah or hell no?
<bot>: Want to put girlfriends number on craigslist advertising a free tv and have her phone blown up with texts, don't want her to get super mad at me, or me have a criminal charge.
