So a load of "you're so old" jokes on another site made me think of this, what could be Star Trek "You're so old" jokes be? Here are some to start off.. You're so old, your first "first contact day" WAS first contact day. You're so old you remember when replicators were called food synthesizers. You're so old your first Phaser only had two settings, stun & kill - it was best not to confuse them. You're so old, to you warp 2 is fast. You're so old you remember when Starfleet was called UESPA.
You're so old, Lela Dax called you "Old Man". You're so old, you wouldn't need a holodeck to see Fair Haven. You're so old, you had a front row seat for the Eugenics Wars. You're so old, you served on the Enterprise. No, not the NCC-1701... No, not the NX-01... You were on the CVN-65!
When you were born, your parents were dancing around... because their feet were on fire. The earth's surface was still molten back then.
