'tis the season

It's that time of year.  Time to break out the sunscreen (which is seemingly made of acid), bug spray (which also elicits the same reaction unless he watches his cousins apply it first in which case it causes him no pain at all), and band aids (which appear to hurt him more than his actual injury).  Harrison's knees suffer even more than usual during the warmer months because he doesn't have that extra layer of pant fabric to protect him.  Poor guy - I'm surprised that he has any skin left on his knees.

Looks like it's also the season for knee pads!
