A similar conversation in 1998 would have gone a little differently.
Shawn: "You and those damn acronyms... can't you just say 'ha ha that is funny?'"
(it took "lol" and "wtf" a while to become common use, too)
Random person sent a happy birthday greeting to a wrong number, and received back a rather strange reply.
I guess her thought-out-plan is blackmailing her mother.
The question is, if she's out celebrating, where's Joey? Sitting at home alone while he reads happy birthday texts from people who are partying without him? Diff'rent strokes, I guess.
From the submitter:
"Uh. I mean. Yeah! How dare you forget! Buy me a new car?"
Let's be honest, saying that sex will be your significant others' only birthday present is a little cheap. Unless he or she would normally pay for it. In which case you're a prostitute, not a lover.
