I've met 'tea' used as a verb, in the sense 'provide tea [and cakes/scones/buns...] for'; 'I don't know how I'm going to manage - we've got forty parties to be
tead and toileted'. But this isn't a usage you'd want to teach. (It's worth remembering the old dictum though: 'Most any noun can be verbed.')

PS On the subject of /ti:/, there
is a verb 'te
e', usually met in the phrasal verbs 'tee up' and 'tee off'. There's also the fairly informal 'gee' (/ʤi:/), most common in 'gee up'. And 'knee' - ' hit with the knee' - as in ('Ref, send him off - He
kneed the goalie in the groin!'). And 'pee', of course, though maybe not in mixed company.
