Go ahead, pull my finger. For most the pulling of another's finger, especially if it's dad or even an uncle's is silly potty humor often resulting in only a fart that will surely cause a few giggles and maybe even widespread laughter. Our pull my finger design features an old hand grenade with the classic slogan. Caution: Beware the one who wears this tee as you have been forewarned that an unimaginable explosion of nasty will surely overcome you should you decide to pull that finger. WTF.
