Woody's pretend watch at the 2020 Trials.

No one mentioned before:

Yohan Blake's chewing gum and claws

Soufiane El Bakkali gritting his teeth past Girma every time and celebrating like a kid at the finish line

Jakob Ingebrigtsen's cheering to the crowd

Sha'Carri Richardson's cross gesture

Karsten Warholm's scream

Keely Hodgkinson's different hairstyle every time

Jessica Hull's unique voice

Karoline Grovdal's DNFs

Adelle Tracey's smile

Josh Kerr's shades

Timothy Cheruiyot's forward lean

Mary Moraa's backward lean

Anna Ryzhykova's braid and claws

Viktoriya Tkachuk's blowing kisses
