Master of Physical Therapy Puns

So I just met a master jokester. The setting:

I came out of work across the parking lot and a car comes at me. So I cross and I hear him go, 'youre walking too fast for this place' it's a 55+ community. So I walk over to talk to him and he goes 'what are you doin here your awfully young to be here'

me: yeaah, I'm 10 years to young. I'm the new chef for your clubhouse'

Him: 'youll be cooking for old men'

Me: 'its a challenge'

Him: 'well I don't want to keep you

Me: 'im just picking my dad up from physical therapy'

Him deadpan, 'well you might not want to do that'

Me: why?!

Him dead serious: well, because he's got to be heavy

Me: ... I can't believe I just got grandpop joked

Him: you better believe it
