Someone has a sense of humor

It deserves a standing ovation.

I dunno, I worked with a guy with the plate "LIGMA" once

It's a South Park reference. Handicap kid named Timmy who communicates saying "Timaay". The vanity being spelt this way along with being a handicap plate is what makes it perfect.

This is your time!

I'm behind you with "TI TIMAH."

Timmy is a character from the show South Park who is physically disabled and his name is often said like "TIMAAY" or even "TIMMAY". I'm biased towards the latter.
