Young Axl called his tax preparer to set a time for he and old Axl to come in, saying "You see, I time traveled and now there are two Axl's..."

The crusty old biddie at H&R block took a deep draw on her Lucky Strike and said "Hey, no need to bullshit me, save that for the IRS."

"But it's no bullshit, really."

"Whatever, dude. Oh, I don't need you and some other imposter to come in here, that is wholly unnecessary: all you need to do is file an amended return to report the additional income."

"Really? I don't need to explain how I travel through time?"

"Just pay me my fee and you can travel where ever the hell you want to."
