| Way back |
| Back when |
| Way back when |
| Way, way back |
| In olden days |
| Way in the past |
| Back in the day |
| In the far past |
| In days of yore |
| Once upon a time |
| Long in the past |
| A long time past |
| A good while back |
| Quite a while back |
| In the distant past |
| In the very old days |
| Way back when: 2 wds. |
| When dinosaurs roamed |
| Way in the past: 2 wds. |
| A long time in the past |
| Way back in the past: 2 wds. |
| Before any of us can remember, perhaps |
