Yes, I did make one of these. You know what to do, questions submitted by PM only, but feel free to review AIG you like this. Thanks.
FBA: (Is watching Boss Mabel on Gravity Falls with a note pad. Occasionally writes something down) I never realized Dipper made two people to insane... parallels! I'm keeping that...
(While she looks at her phone screen, a small hole in the space-time continuum opens up)
Bill: Wrong dimension! (Exits back through portal/time thing)
(FBA looks up, and stops the video)
FBA: ...I've been at this for too long. I could have sworn I heard-
(Bill pops out of nowhere)
Bill: Me?
FBA: AAAHHH! (Falls out of chair)
Bill: So it's this dimension...
FBA: (Looks up) Well, I'm dreaming again.
Bill: I think I'd know if you were, kid.
FBA: Don't call me a kid! (Crosses arms) I make the rules!
Bill: (Laughs) Really? Well, go back to your obsessive little group, I'm busy! (Starts to leave through portal thing again)
FBA: Wait... WAITWAITWAITWAITWAIT!
Bill: (Sighs) Here we go...
FBA: I have so many questions! What dimension did you come from?! Are you a triangle or a pyramid?! How do you know Stan?! Are you Gompers the goat?! WHAT HAPPENS IN SEASON 2?!
Bill: I don't have to answer your questions. (Large clock appears beside him) I have a schedule to keep! (Starts to leave for the second time)
FBA: ...Is this the part of my dream I make a deal with you? (Bill pauses at the word "deal")
Bill: And what do you have that I could be interested in? (He turns around to face FBA)
FBA: Can you answer a quick question first?
Bill: Sure. (Target appears in front of him) Hit me with it, kid.
FBA: This is going to sound stupid, but do parallel universes exist?
Bill: (Target disappears) You bet they do! Every single character created by the mind has it's own reality!
FBA: (Grins) Then you know what I'm going to offer...
Bill: You're one of those FanFiction writers, right? And you're offering to help the Bill in your story somehow.
FBA: Yep! Here's my deal: If you answer some questions more of your fans send in, I'll make sure something... unfortunate happens to the Pine twins while they're battling Bil- er, you.
Bill: (Rests hand right above his bow tie and appears to be thinking) Hmm... you've got a deal! (Reaches arm out as blue fire engulfs it. FBA looks away for a second)
FBA: Sheesh, that's bright! (Extends arm and shakes)
Bill: Great! I'll just pop back whenever you get a couple questions from your little friends. (Disappears in blue flame)
FBA: (Blinks) Well that just happened. Huh. I'll have to put this on FanFiction ASAP...
