Common Law Daughter-In-Law

Yesterday I received an email from my son's girlfriend.....they live together in Tennessee. (much to my chagrin) This is the first email I've ever gotten from her, she never calls me and makes no attempt at all to have a relationship with me. That's fine, no biggie.
Anyway......the email contained an attachment. I opened it and it's a video of some guy with a HUGE "member" playing a not so real piano (large piece of material that looked like piano keys draped in front of him), slinging his huge dick to the tune of the music. Yes, I did watch it and laugh.
BUT, it's not very appropriate to send this to your boyfriend's MOTHER. Especially when there's no relationship involved.
(That guy on the video was a "hung-dinger"! Holy Cow! Yikes! ...and NO freakin' way! ::grin::)
