That was one SICKO movie ...
Lessons to be learned:
DON'T DO IT !
If you DO,
Don't take her to YOUR house,
Don't give your REAL phone number,
Don't tell her where you work,
Don't go back to the place you met,
And most important,
DON'T DO IT !!!
Of course, in Dave's case it's different - he's a single guy ...
