Yep...never a dull moment with a toddler...
My toddler went thru a phase like that. I just kept my poker face and didn't show any reaction. After some time she got tired of fighting and realized it was no use.
She also had a phase where she'd throw a huge tantrum when it was bedtime. I would just go about our bedtime routine (even if it meant holding her down while brushing her teeth) and after 3 weeks, she finally stopped throwing tantrums.
Even now, my toddler hates getting her shirt off in the mornings. So I've taken to putting her to bed with the shirt on that she would wear the next day, so there is no hassle of trying to yank off her shirt.
So this is a common thing toddlers do...Don't give him an audience, be stoic, keep being persistent in dressing him, and it will pass.
